BOTAN Digipeater Schedule a Challenge for U.S. Hams

BOTAN, a 1U cubesat built by students of the Chiba Institute of Technology
in Japan, was deployed from the International Space Station (ISS) on
October 10 via the Japanese Space Agency (JAXA) ?Kibo? modu
le. The
satellite carries an earth-observation camera downloading images upon
ground station command at 437.375 MHz. These downloads occur primarily when
the satellite is over Japan.

Information on the satellite may be found at https://sites.google.com/p.chibakoudai.jp/gardens-04/home-english?authuser
?
BOTAN also carries an APRS digipeater operating on 146.825 MHz. The
digipeater is also activated by ground station command. Although the
original design specifications called for the digipeater to remain active
for 720 minutes (12 hours) after activation, observations have shown that
it currently times out after 480 minutes (8 hours).

As a result, when the digipeater is activated by the command station in
Japan, it has timed out before passing over portions of North America.
Although the Chiba Institute has asked amateurs around the world for
telemetry downloads, the attempts to make use of the satellite?s se
rvices
have been frustrating for North American amateurs.

BOTAN is next scheduled for digipeater activation on 2025-11-16 at 08:53
UTC (although current Keplerian data does not show the bird over Japan
until approximately half an hour after that time). Far west coast U.S. and Mexican stations would be in the footprint briefly in the first hour thereafter. The eight hour activation would end at 16:53 UTC. During that period the satellite will pass over Asia, Australia, Africa, Europe, and
South America ? but not over Central or North America. Interested o
perators
are encouraged to watch for schedule changes.

Masahiro Sanada, JI1IZR, has posted a nice blog about the station setup he
is using for BOTAN operation. The post may be found at https://ji1izr.cocolog-nifty.com/

Launch Scrubbed Due to ?Highly Elevated Solar Activity?

After terrestrial weather forced Blue Origin to scrub its Sunday attempt to launch its 98-meter-tall (321 ft) New Glenn rocket, unacceptable space
weather prevented a launch attempt on Wednesday from Cape Canaveral Space
Force Station.

In a post on social media, the company said NASA made the call to stand
down ?due to highly elevated solar activity and its potential effec
ts on
the ESCAPADE spacecraft.?

On Tuesday afternoon, NOAA?s Space Weather Prediction Center foreca
st a G4
Severe Watch connected to a coronal mass ejection first detected on Sunday, Nov. 9. It noted that this is just the fourth G4 Watch issued this solar
cycle, making it ?very rare,? and added that impacts are ex
pected ?about
midday on Nov. 12.?

A severe (G4) geomagnetic storm lit up skies across the Northern Hemisphere overnight (Nov. 11-12), with vivid northern lights visible across Canada,
the U.S, and as far south as Mexico.

The incredible display followed the arrival of multiple coronal mass
ejections (CMEs) ? eruptions of magnetic field and plasma from the
sun ?
launched by sunspot AR4274, one of the most energetic sunspot groups of the current solar cycle. The ongoing storm ranks among the strongest of Solar
Cycle 25 and last night?s peak at G4 clocked in as the third strong
est
geomagnetic storm this solar cycle. The first two CMEs struck in quick succession last night, compressing Earth?s magnetic field and unlea
shing
spectacular aurora shows that lasted well into the night.

Blue Origin finally launched its second heavy-lift New Glenn rocket
Thursday, Nov. 13, putting two small NASA satellites onto a long, looping course to Mars to learn more about how the sun has slowly blown away the
red planet?s once thick atmosphere.

Alarm Over Reductions at Goddard Space Flight Center

Alarm is growing among federal workers at NASA?s iconic Goddard Spa
ce
Flight Center?s main campus in Greenbelt, Maryland ? the ne
rve center for
groundbreaking missions like the Hubble and James Webb space telescopes ?
??
as more than a dozen buildings on the campus are being emptied and
padlocked during the federal shutdown, with very little notice to
employees, said four sources who spoke to CNN on the condition of anonymity
for fear of retribution. NASA leadership has pushed back against those concerns.

In one instance, furloughed employees were given just days to temporarily return to work and help empty entire buildings of highly specialized
equipment, according to sources and internal emails obtained by CNN. In the communications, NASA managers wrote that equipment not moved in time ?
?
including one-of-a-kind hardware ? could be thrown away or donated.

In a statement, a NASA spokesperson said the building closures are part of
a ?strategic consolidation? plan mapped out by Goddard lead
ers that should
not impact ongoing projects.

One document reviewed by CNN, which was compiled by more than a dozen
Goddard workers concerned about the steps taken at the campus, states that
13 buildings are being shuttered, including about 100 laboratories. The
roughly 1,270-acre campus includes more than 30 large buildings and dozens
of smaller structures.

The changes described by sources have the space agency?s engineers
concerned they could permanently lose access to equipment and facilities
that are crucial to keeping current and future projects on track.

Comet Photos Plagued by Satellite Streaks

Recent months have seen space fans revel in a wealth of spectacular astrophotography depicting the evolution of Comet Lemmon?s glowing
coma and
twisting tail as it journeyed through a Northern Hemisphere night sky
swarming with satellites.

While many photographers opted to post sanitized views of Comet Lemmon,
others intentionally compiled their images to reveal the incredible number
of satellites that crossed the night sky over the course of multiple
exposures.

rejected by an image-stacking algorithm. (Image credit: Dan Bartlett via Space.com)*

?Photographically, if someone is attempting to take a single image
of a
target and needs the image to be ?clean? ? free of
manmade objects ? well,
that image is nearly impossible to obtain,? astrophotographer Dan B
artlett
told Space.com in an email. ?Every single subframe I take (prior to
stacking) now contains at least one, and usually more than one satellite streak.?

There are currently about 13,000 operational satellites orbiting Earth, of which about 8,900 are SpaceX Starlink craft. This number is set to exponentially increase, with SpaceX alone aiming to orbit up to 42,000 of
its internet-beaming spacecraft, while competing companies aim to add
thousands more satellites to their own ?megaconstellations.?
?

Astrophotographers combat satellite streaks by capturing a multitude of
short exposures over the course of a single session. The images are then combined and subjected to an algorithm that determines a median value for
each pixel before rejecting outlier pixels with values that exceed set parameters.

Changes to AMSAT TLE Distribution for November 14, 2025

Two Line Elements or TLEs, often referred to as Keplerian elements or keps
in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin
files are updated daily in the first hour of the UTC day. New bulletin
files will be posted immediately after reliable elements become available
for new amateur satellites. More information may be found at
https://www.amsat.org/keplerian-elements-resources/ <https://www.amsat.org/keplerian-elements-resources/>.

The following satellite has been *removed* from this week?s AMSAT
distribution:

*ENSO* ? NORAD Cat ID 58470 Decayed from orbit on or about 09 Novem
ber 2025

The following satellite has been *added* to this week?s AMSAT distr
ibution:

*CEVROSAT1* ? Provisional ID 98526 *Note: Resource constraints at U
SSF
18SDS evidently are preventing generation of TLE for this satellite. The element set provided is unusally poor, expect the satellite to pass a
minute or more away from predictions.*

ARISS SSTV Event Continues

The worldwide Amateur Radio on the International Space Station (ARISS) team
and the global family of ham radio enthusiasts celebrated 25 years of continuous amateur radio operations on the International Space Station
(ISS) on November 13, 2025.

Only eleven days after the Expedition 1 crew took up residence on ISS the
crew turned on the ham radio system and began speaking with teams in Star
City Russia, the NASA Goddard Space Flight Center in Greenbelt, Maryland,
and the NASA Johnson Space Center in Houston, Texas.

Throughout it all volunteer ARISS team members have worked side by side
with space agencies and astronauts and cosmonauts around the world to
develop, certify, launch and operate the ham radio systems that enable
creation of an amateur radio bridge between people on earth and spacefarers
in orbit.

During 25 years of continuous operations, ARISS has connected 1 million
kids in classrooms and information educational settings to the ISS through nearly 1,800 ham radio contacts. It?s all about Science, Technology
,
Engineering and Math (STEM) educational opportunities. Maximum value is
added by working with educators to ensure that their students learn about
space science, living and working in space, ISS research and radio communications. This educational element starts 4-6 months before the ARISS contact.

When the time comes for their once-in-a-lifetime radio contact with the
ISS, they use an amateur radio ground station at their host organization or
one of our international ground stations to talk directly to the astronauts
and cosmonauts on ISS?LIVE!

There are two amateur radio stations on ISS, one in the Columbus Module and
one in the Service Module, supporting 24/7 communications with hams on the ground via voice and digital repeaters in space. ARISS also provides opportunities for youth and radio amateurs to downlink pictures, called
Slow Scan Television (SSTV), from ISS as well as standard Television
downlinks using our HamTV system and our L/S-Band antennas.

It?s important to note that these amateur radio systems are complet
ely
independent from the ISS communications systems. Because of that, they also serve as a pivotal ISS backup communications capability. If the main ISS communications systems fail or are rendered unusable, our flight hardware
and ground operations team is ready to spring into action 24/7.

As we cross the threshold of 25 years of continuous operations on ISS and
look forward to many more, ARISS will begin a one-year commemoration of its achievements. Several interactive initiatives for youth, educators, ham
radio operators and the public are planned. Stay tuned to the ARISS website
and social media channels to find out what what is planned. As
reported in *AMSAT
News Service* bulletins last week, the first commemorative event is already underway?an SSTV (picture downlink) event that started November 12
and runs
through November 19.

Many times a school may make a last minute decision to do a Livestream or
run into a last minute glitch requiring a change of the URL but we at ARISS
may not get the URL in time for publication. You can always check https://live.ariss.org/ to see if a school is Livestreaming.

As always, if there is an EVA, a docking, or an undocking; the ARISS radios
are turned off as part of the safety protocol.

The crossband repeater continues to be *active* (145.990 MHz up {PL 67} & 437.800 MHz down), If any crewmember is so inclined, all they have to do
is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know.

Packet operations (145.825 MHz up & down) *suspended* for SSTV (145.800 MHz down) until November 20.

Ham TV is *configured* for scheduled digital amateur television operations (2395.00 MHz).

Note, all times are approximate. It is recommended that you do your own
orbital prediction or start listening about 10 minutes before the listed
time.

The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html

planned to use was damaged, likely from being hit by space debris. The team left their Shenzhou-20 spacecraft in orbit and came back using the recently arrived Shenzhou-21, which had ferried a three-person replacement crew to
the station, China?s Manned Space Agency said. The original return
plan was
scrapped because a window in the Shenzhou-20 capsule had tiny cracks, most likely caused by impact from space debris, the space agency said Friday.
