On July 11 a total solar eclipse was observed in the southern Pacific =
Ocean. The path of totality stretched across the South Pacific Ocean, =
but the Moon's umbral shadow didn't make landfall except for a few =
spots such as the Cook Islands and Easter Island, and southern Chile =
and Argentina. A partial eclipse was visible from a much larger region =
covering the South Pacific and southern South America. =
Masa, JN1GKZ noted a glitch in AO-51's Whole Orbit Data file (WOD) =
in the Total Array I current while AO-51 was located east of Argentina =
at the time. AO-51 Control Station, Mark, N8MH replied, "You have made =
a great observation, and I think you are exactly right about the cause =
of the observed 'glitches' in the telemetry. Usually at this point in =
its orbit we would observe AO-51 charging its batteries at a steady =
rate from fully illuminated panels."
Mark plotted some of the telemetry collected from 1800-2130utc) and =
posted it at:

Alex, OZ9AEC ran a simulation using the Celestia space simulator and =
observed a partial solar eclipse as seen from AO-51. He recorded this
simulation to a video and you can watch at:

For several days last week, Colonel Doug Wheelock, KF5BOC, took to =
the air from the ISS to talk to hams around the globe. The 2-meter
FM phone frequencies for voice operation with the ISS over the US =
are 144.490 MHz uplink with 145.800 MHz downlink.
Dee, NB2F noted, "I Just talked with the ISS. Loud and Clear. Good =
sigs and thanks to the ISS crew for making contacts." Damon, WA4HFN =
wrote, "I made my first ISS voice contact with NA1SS. He was full =
meter reading!" Greg, KO6TH also noted the strong downlink signal.
Later in the week the ISS crew activated the SSTV equipment to support
the Moscow Aviation Institute experiment (MAI-75) on July 15 and 16. =

WA8SME conducted the Dayton Amateur Radio Association sponsored =
ARRL TI-2 Teacher's Institute - Space this week in Dayton. The =
purpose of this teacher's institute is to instruct teachers on =
how to access satellites for use in their classrooms. The four =
day institute will involve a lot of on-the-air activity on the =
birds. =
Concluding a successful session, Mark wrote, "I want to offer my =
sincerest thanks to the satellite community, Drew, and AMSAT for =
the support that you gave us during the TI-2 Space this year. Over =
the last three days, your support in making contacts with the tea-
chers, and in particular, the dedicated SSTV activity on AO51, has =
made the TI-2 Space a huge success this year. I wish each of you =
could have seen the glowing light bulbs in the teachers' heads at =
each successful satellite contact. I am confident that they will =
be taking what they learned this week back into their classrooms =
to make space 'alive' for their students. Thanks for the patience =
you showed as these novice satellite operators learned the tricks
of the trade."
Mark also noted the success of having 8 satellite ground stations, =
and antennas operating at one time.

Satellite Centre in India, Mani, VU2WMY said the July 12 launch of
the 17th flight launch of Indian space agency's Polar Satellite =
Launch Vehicle PSLV-C 15 from Sriharikota was successful. Mani wrote,
"All the five satellites including the StudSat and TISat aboard the =
PSLV-C15 were successfully separated from the vehicle and they are =
in the [correct] 640 Km orbit right now."
The PSLV-C15 launch included a primary payload of the CartoSat-2B
remote sensing satellite and AlSat-2A satellite. The three other
satellites included AISSat-1, a Norwegian Defence Research Establish-
ment satellit to demonstrate a new maritime AIS receiver; and the =
TISat-1 and StudSat amateur radio banded cubesat payloads.
TIsat-1: Swiss CubeSat

Paolo, HB9TYP says TIsat-1 is in power/battery saving mode during =
eclipse. Its transmission is limited or completely shut off according =
to on board rules. On behalf of the TIsat-1 team Paolo thanks the AMSAT =
community for signal reports already received. He says you can find the
latest keps and other details on the project and mission status webpages:
http://www.spacelab.dti.supsi.ch/tiSat1MS.php. The TIsat-1 team invites
your continued feedback. While copying the beacon please collect and =
report the character emitted AFTER "HI HI HI TISAT" along with time in =
UTC, your location and signal quality.

third-party logging program. The app was developed by VE2ZAZ, and =
uses colors to display information on a per-band basis. Up to four =
bands can be displayed concurrently. For its input, the program =
reads the plain-text ASCII log files generated by most logging pro-
grams. The file is read at a set interval and the worked grid squares =
on the map are updated in a dynamic way as the contest progresses =
and the log file is periodically saved. WorkedGrids can be down-
loaded from http://tinyurl.com/24okrtm.

In addition to regular membership, AMSAT offers membership in the
President's Club. Members of the President's Club, as sustaining donors
to AMSAT Project Funds, will be eligible to receive additional benefits.
Application forms are available from the AMSAT Office. And with that
please keep in mind the young ham who got a job in the shoe factory but
found that he didn't fit in. When he tried working at the deli they told
him he didn't cut the mustard. He found that he just wasn't up to it in
his latest job feeding the giraffes at the zoo.
