First X-Class Major Solar Flare of Solar Cycle 25 Blacks Out HF on July
3
For a brief time on July 3, a lot of radio amateurs were wondering,
"Where did the bands go?" as the first X-class solar flare in 4 years
blacked out HF propagation for a time.
"I was on 20-meter FT8, and my waterfall display went from solid red
signals to solid nothing in the blink of an eye," Scott Craig, WA4TTK,
told "K7RA Solar Update" Editor Tad Cook, K7RA. "It lasted about 10
minutes." Craig was not alone.
"Many American radio amateurs reported sudden HF propagation blackouts
on Saturday morning, July 3, when solar active region 12838 produced an
X1.5 major solar flare that reached maximum intensity at 1429 UTC, the
first X-class solar flare of Solar Cycle 25 and the first since 2017,"
said Frank Donovan, W3LPL. "HF propagation blackouts are caused when
x-ray and extreme ultraviolet radiation from X-class solar flares
strongly ionizes the absorbing D-region in the Earth's sun-facing dense
lower ionosphere," he explained.
In this instance, it caused what NOAA's Space Weather Prediction Center
(SWPC) calls an R3-level or "strong" radio blackout (on a scale of R1 -
R5). An R3 incident can cause a "wide-area blackout of HF radio
communication [and] loss of radio contact for about an hour on [the]
sunlit side of Earth. Low-frequency navigation signals degraded for
about an hour."
Donovan said that X-class major solar flares are necessary consequences
of steadily increasing Solar Cycle 25 activity. "95% of all X-class
solar flares occur when the solar flux index is 90 or greater. The
remaining 5% can occur any time during the solar cycle," he points out.
"X1-class major solar flares typically degrade HF propagation for only
an hour or two at mid and high latitudes, only on Earth's sunlit side."
X-class major flares are measured on an open-ended scale. The strongest
one ever recorded was an X28 flare in 2003, hundreds of times more
powerful than the July 3 X1.5 solar flare. X10-class and stronger solar
flares typically have effects that last for most of a day and affect
the entire sunlit side of the Earth. Fortunately, X10-class solar
flares occur only about once every 20 years or more.
"Much more severe and long-lasting HF propagation degradations are
often caused by the coronal mass ejections (CMEs) often associated with
-- but not caused by -- major solar flares," Donovan explained. "HF
propagation degradation caused by CMEs typically begins about 2 days
after the effects of the associated solar flare, the duration of the
delay depending on interactions between the CME and the solar wind."
The CME associated with the July 3 X1.5 solar flare is likely to have
little to no effect on HF propagation going forward, because the active
region was very close to the western edge of the visible solar disk
when the CME erupted. Region 12838 rotated off the visible disk on
Sunday, July 4.
Solar flares have no significant effect on VHF ionospheric propagation,
but can degrade satellite communications passing through the
ionosphere. More frequent, less powerful M-class medium solar flares
produce short-duration degradation at high latitudes. Very frequent,
much weaker A-, B-, and C-class solar flares do not degrade HF
propagation. -- Thanks to Frank Donovan, W3LPL
Amateur Radio Volunteers Prepared for and Tracked Elsa
The weather event known as Elsa, a tropical storm that also achieved
Category 1 hurricane status, prompted actions by ARRL, the Amateur
Radio Emergency Service (ARES), and the Hurricane Watch Net (HWN) as
the storm set its sights on Florida this week. The storm made landfall
along the Gulf Coast of northern Florida on July 7, before weakening
significantly.
As Tropical Storm Elsa moved up the East Coast, the Eastern New York
(ENY) and New York-Long Island (NLI) Sections received a request from
the American Red Cross (ARC) Greater New York Region to have ARES
groups put on alert from July 9 through July 15.
"As of now, it's just preliminary planning with no definite plans for
opening shelters or service delivery sites," Phil Nelson, N2PN,
Regional Field Communications Manager of ARC Greater New York said on
July 7.
"Please stay aware of developing conditions," Eastern New York Section
Emergency Coordinator (SEC) Dave Galletly, KM2O, urged. "I ask that
groups in the ENY Southern District prepare for possible deployment in
support of ARC as of Friday, July 9. Groups in the Central and Northern
Districts should also keep in touch with weather developments and stand
by for possible mid to long-term support of Southern District groups."
On July 6, Northern Florida SEC Karl Martin, K4HBN, activated the ARES
Net on 3.950 kHz. An open net was activated on SARnet -- a UHF-linked
repeater network. As the evening developed, the Section saw six
emergency operations centers and many shelters open. The Northern
Florida Section stood down from a Level III monitoring activation on
July 7.
"ARRL Headquarters and the ARRL Emergency Management Department are
monitoring the storm's progress and will be ready to assist Sections
affected by Elsa," ARRL Emergency Management Director Paul Gilbert,
KE5ZW, assured as the storm approached.
The Hurricane Watch Net initially activated for Elsa on July 2, after
it became a Category 1 hurricane.
"Because the storm was extremely close to Barbados, St. Lucia, and St.
Vincent, we went into operation to collect and forward weather data to
the National Hurricane Center in Miami," Net Manager Bobby Graves,
KB5HAV, said. The HWN reactivated for several hours on July 6, standing
down after about 8 hours.
Elsa has produced some wind damage, but the major hazard from the storm
so far appears to be heavy rain, flooding, and storm surge. Some
suspected tornadoes have been reported. Elsa is expected to move across
the southeastern and mid-Atlantic US.

June 2021 Volunteer Monitor Program Report Released
The June 2021 activity report of the Volunteer Monitoring (VM) Program
has been released. The VM Program is a joint initiative between ARRL
and the FCC to enhance compliance in the Amateur Radio Service.
* The FCC was requested to review a vanity call sign application
filed by a Georgia licensee because of an apparently false answer
to the question regarding a felony conviction.
* A licensee in Massachusetts received an visory Notice concerning
obscenity and harassment on 160 meters. The FCC will hold for
review any renewal application filed by this licensee.
* A General-class licensee in San Antonio, Texas, received an
visory Notice for operation in the Amateur Extra-class portion of
the 20-meter band.
* Licensees in Pennsylvania, North Carolina, Georgia, and Virginia
received visory Notices concerning failure to identify and other
possible violations as part of a general audit of complaints about
licensee conduct on 1.938, 3.860, 3.895, and 3.927 MHz.
* In May, Volunteer Monitors logged 1,514 hours on HF frequencies and
2,072 hours on VHF frequencies and above.
The Volunteer Monitor Program ministrator had one meeting with the
FCC, and two cases were referred to the FCC for further action. One
case involves a taxi company in Alaska operating on 2 meters. -- Thanks
to Volunteer Monitor Program ministrator Riley Hollingsworth, K4ZDH

Young Caribbean Nation Formalizing Amateur Radio Guidelines and
Standards
With a population just north of 71,000, the Caribbean island of
Dominica (J7) boasts a modest but active ham radio population. Given
Dominica's vulnerability to hurricanes, the ham radio emphasis often
focuses on emergency communications support. In 2017, after Hurricane
Maria hit the tiny island, ham radio filled a huge telecommunications
gap. Now the country's telecommunications regulator is asking hams to
help formulate new amateur radio guidelines and standards. Dominica's
National Telecommunication Regulatory Commission (NTRC) is collecting
comments until July 12 from radio amateurs participating in a
"consultation" (what the US FCC would call a "proceeding") that could
lead to a formal and better-documented set of rules and regulations.
"There is limited guidance for those who seek to utilize the
telecommunications media for their own personal use, enjoyment, and
fulfillment as [a] hobby, as in the case of amateur radio," the NTRC
said in the consultation document. "Generally, [amateur radio] is
self-regulating, and so the involvement of the telecommunications
regulator is minimized. Though the amateur radio clubs generally do
their best to provide some level of guidance and support to existing
and prospective operators, there is great need for a formal and
comprehensive set of guidelines and standards for the operation of
Amateur Radio Services in Dominica."
Resources used in developing the draft proposals included ARRL, the
FCC's Part 97 amateur radio rules, and the International
Telecommunication Union (ITU).
"A primary source for this document was the Code of Federal Regulations
(Title 47, Part 97), due to its comprehensiveness and its informal
adoption in certain parts by the local amateur radio fraternity," the
NTRC said. Specific ARRL resources included The ARRL FCC Rule Book; The
ARRL Operating Manual for Radio Amateurs, and The ARRL Handbook for
Radio Communications. The regulators also

emergency preparedness exercise.
looked at Canada's and Australia's amateur radio rules. The proposals
would provide for three license classes -- Novice, General, and
vanced -- as well as licensing procedures for each.
The NTRC held a public meeting via Zoom in mid-June to "highlight and
clarify important issues" regarding the consultation. NTRC personnel
later met with amateur radio club representatives at the NTRC's office.
Under Telecommunications Act No. 8 of 2000 and its associated
regulations, the NTRC oversees compliance with all telecommunication
rules in Dominica, including amateur radio. The NTRC also manages
amateur radio spectrum.
Following the initial comment period, the NTRC will review the comments
and subsequently submit the Revised Draft Amateur Radio Guidelines and
Standards document for comments on the initial comments received. The
NTRC will also review those comments and finalize the policy document,
taking all views into consideration, to adopt and publish the Amateur
Radio Guidelines and Standards document.

Registrations Strong for 24th Annual International Lighthouse Lightship
Weekend
Set for August 21 - 22, the 24th annual International Lighthouse
Lightship Weekend (ILLW) will be back, despite the disruption of the
global COVID-19 pandemic. Each year, typically on the third weekend of
August, participants set up portable stations at or near lighthouses
and lightships around the world. Last year, prospects for the event
were looking dim, but "regular supporters wanted the event to be a
beacon of hope," the event's sponsor said. More than 360 registrations
from 43 countries backed up their belief. As of July 8, this year's
registration tally had already topped 200, with 25 participants signed
up to activate lighthouses or lightships in the US. The ILLW typically
attracts entries for some 500 lighthouses in more than 40 countries.
The event has few rules and is not a typical contest-type event. The
ILLW will begin at 0001 UTC on August 21 and continue through 2400 UTC
on August 22.
Each station's operators decide how they will operate their station
with respect to modes and bands. There are no power restrictions or
entry classes and no scores.
"We wish operators to enjoy themselves and have fun while making
contact with as many amateur radio stations as possible," ILLW said in
the event announcement. "We request that stations take time to work
other lighthouses or lightships, as well as the slow operators or newly
licensed or QRP stations." Participants contact the relevant
authorities to obtain permission to operate. It is within the
guidelines of the event to move operations from a lighthouse to a
museum for historic reasons. In any case, the lighthouse should be
visible to, and visited by, the public wherever possible.
Visit the ILLW website for more detailed information.
NRRL Receives Grants to Support Online Learning, Emergency Preparedness
The Norwegian Radio Relay League (NRRL) has recently received two
substantial grants that will further its education and emergency
preparedness programs. NRRL was given nearly $81,500 from the Research
Council of Norway for the development of teaching material for amateur
radio. According to NRRL, the grant will fund measures that "strengthen
children's and young people's digital competence through leisure
activities." NRRL will develop online learning material for amateur
radio and other activities over the course of the 2-year project.
"Voluntary efforts from NRRL members will also be an important input
factor in the project," NRRL said. "We hope that many will take an
active part in this work, which will be important for the future of
amateur radio in Norway."
NRRL has also received a grant of nearly $94,000 from the Gjensidige
Foundation that will further support its emergency preparedness and
response initiatives. The funds will specifically enable NRRL to
develop and produce new tracking units that NRRL will use in its rescue
service to locate volunteer teams on a map and in real time. In
addition, the funds will support much-needed equipment and joint
exercises and skills development.
"Volunteer rescue crews have been a critical part of the Norwegian
rescue service for more than 50 years," said NRRL's Liaison Service
head, Henrik Solhaug, LA6ETA. "In close cooperation with the police and
the Main Rescue Center, they have, over the years, searched for and
found thousands of missing individuals and saved hundreds of lives.
These are tasks that the public sector itself does not have the
capacity to perform, and volunteers have largely covered the costs
themselves." -- Thanks to NRRL
In Brief...
To keep member records up to date, ARRL emailed Life Members on June
16. A follow-up email will be sent in the next few days, asking them to
verify their mailing address. Be assured that it is a legitimate
request sent from ARRL. Thank you to all those who responded. If you

membership@arrl.org, or respond to the email you received. If your
email client does not recognize the text as a link, you will need to
cut and paste it into a web browser to access the verification web
page.
The QSO Recorder Indexing Service lets you hear your contacts.
Developed by Vasiliy Gokoyev, K3IT, the QSO Recorder Indexing Service
(QSORDEX) allows radio amateurs to share their contest and DXpedition
contact audio recordings. Users then can search the site to retrieve
them by call sign. Audio files are in .mp3 format, saved according to
the system's naming convention, and then uploaded to the Dropbox.com
file-hosting service. The site itself does not store any files; it only
indexes them. To add your own contacts, register at Dropbox.com and
download and install the Dropbox PC client. A free 2 GB Dropbox account
can store approximately 12,000 contacts, although users may purchase
additional space above what is provided with a free account. See the
QSOrder website for additional details.
The CHESS CubeSats will not carry amateur radio payloads. It was
announced in January that two CHESS CubeSats set for launch in 2022
would carry amateur radio linear transponders. The project sponsors
announced on June 10, however, that neither CHESS satellite would
include an amateur radio payload. Citing funding constraints, CHESS
project management had to move the project toward a purely scientific
program using a commercial CubeSat platform, which has less space for
the planned ham radio transponders. CHESS project management also will
not use frequencies allocated to the Amateur Satellite Service, but
will use Earth exploration or experimental UHF and X-band frequencies.
"The ham community, which assured the funding of the transponder, is
very disappointed by this decision but must accept it," the project
team said in a news release. "Such projects always carry risks of one
partner changing its mind. That is what happened here. Many thanks to
all who have actively supported the transponder project, especially the
AMSAT-UK and AMSAT-NL team."
A filing extension has been granted in the FCC space launch proceeding
The FCC Office of Engineering and Technology has granted a 30-day
extension for filing comments and reply comments on the Further Notice
of Proposed Rulemaking in the Non-Federal Space Launch, Federal Earth
Stations, and Federal Space Station proceedings (ET Docket 13-115).
Comments will now be due by August 11, and reply comments will be due
by September 9. As announced in June, the FCC is soliciting a second
round of comments on whether to authorize commercial space entities to
obtain licenses for frequencies used exclusively during space launch
activities. The proposals include parts of the 70-centimeter (420 - 430
MHz) and 5-centimeter (5650 - 5925 MHz) bands.

The K7RA Solar Update
Tad Cook, K7RA, Seattle, reports:
Solar activity continues to increase. The average daily sunspot number
was 34.7 last week; this week it jumped to 55.6. Average daily solar
flux increased from 86.9 to 88.9.
Despite solar flare activity pushing a sudden ionospheric disturbance
and a dramatic HF radio blackout (see "First X-Class Major Solar Flare
of Solar Cycle 25 Blacks Out HF on July 3"), at least the average daily
planetary A index for the week was only 5.7, down from 6.1 last week.
The average middle latitude A index was also 6.1 last week, and it was
6.3 this week.
The flare was an X1.5-class event, the biggest since September 2017 and
the only X-Class solar flare since then. Events such as this can be so
dramatic that some may initially assume a hardware or antenna failure.
Fortunately, these are rare.
Predicted solar flux is 76 on July 8; 74 on July 9 - 11; 72 on July 12
- 13; 70 and 74 on July 14 - 15; 82 on July 16 - 18; 84 on July 19; 88
on July 20 - 22; 90 on July 23 - 28; 88 on July 29 - August 2; 84 on
August 3; 82 on August 4 - 5, and 80 on August 6 - 11.
Predicted planetary A index is 5, 8, 12, 8, 12, 16, and 8 on July 8 -
14; 5 on July 15 - 17; 15, 12, and 10 on July 18 - 20; 5 on July 21 -
31; 10 and 8 on August 1 - 2; 5 on August 3 - 5; 15 and 12 on August 6
- 7, and 5 on August 8 - 13.
Sunspot numbers for July 1 - 7 were 56, 72, 81, 60, 43, 52, and 25,
with a mean of 34.7. The 10.7-centimeter flux was 94.1, 94.9, 93.7,
91.1, 89.4, 83.2, and 76, with a mean of 86.9. Estimated planetary A
indices were 7, 5, 4, 3, 7, 8, and 6, with a mean of 6.1. Middle
latitude A index was 7, 6, 4, 4, 9, 8, and 6, with a mean of 6.1.
A comprehensive K7RA Solar Update is posted Fridays on the ARRL
website. For more information concerning radio propagation, visit the
ARRL Technical Information Service, read "What the Numbers Mean...,"
and check out this Propagation Page.
A propagation bulletin archive is available. For customizable
