AMSAT NEWS SERVICE
ANS-029

The AMSAT News Service bulletins are a free, weekly news and infor-
mation service of AMSAT North America, The Radio Amateur Satellite
Corporation. ANS publishes news related to Amateur Radio in Space
including reports on the activities of a worldwide group of Amateur
Radio operators who share an active interest in designing, building,
launching and communicating through analog and digital Amateur Radio
satellites.

The news feed on http://www.amsat.org publishes news of Amateur
Radio in Space as soon as our volunteers can post it.

Please send any amateur satellite news or reports to:
ans-editor at amsat.org.

In this edition:

* Colloquium Videos for 2009-2012 Posted on YouTube
* ARRL LoTW Adds Additional Satellite Entries
* Upcoming ARISS Contact Schedule as of 2017-01-27

Colloquium Videos for 2009-2012 Posted on YouTube

AMSAT-UK reports that thanks to Wouter Weggelaar PA3WEG and @BATC online 
videos
of talks given at AMSAT-UK Colloquium 2009-2012 are now posted at
https://www.youtube.com/user/AMSATUK/videos

The videos were made by members of the British Amateur Television Club 
(BATC)
and stored on the club’s streaming site. Dedicated BATC members have 
carried out
the world-wide streaming and recording of the  AMSAT-UK International Space
Colloquium since 2007.

Get Your Iridium Fix Before It’s Too Late!

The shock and dazzle of Iridium flares will soon be a thing of the past. 
Here's
how to make the most of seeing them before a new generation of spacecraft
replaces the Iridium satellites.

Each of the approximately 66 Iridiums in orbit have three door-sized 
aluminum
antennae treated with highly reflective, silver-coated Teflon for 
temperature
control.

When the angle between observer and satellite is just right, sunlight 
reflecting
off an antenna can cause the satellite to surge from invisibility up to
magnitude –8.5 in a matter of seconds. If you've never seen one, the searing
brilliance may make you recoil instinctively. On rare occasions, flares can
reach magnitude –9.5. That's 100 times brighter than Venus!

Sadly, that era will soon draw to a close. On January 14th, SpaceX’s 
Falcon 9
delivered the first 10 of a new generation of Iridium NEXT satellites to 
low-
Earth orbit, starting the process to replace the older units in a maneuver
called slot-swapping. While the new birds will provide faster data rates and
enhanced global communications, their antenna design is completely 
different and
not expected to produce significant flares.

Heavens Above is one of the easiest sites to get you looking in the 
right place
at the right time. The Heavens Above website allows for easy figuring and
finding of Iridium flares.

Just sign in and give it your location, then click the Iridium Flares 
link under
the Satellites heading on the left side of the homepage. A table will 
pop open
with a week's worth of passes that includes pertinent information like
brightness, altitude, and magnitude of the flare at flare center, the 
brightest
possible magnitude for a particular pass. Clicking on the date will 
produce a
map showing the flare's path and ground track where the flare will appear
brightest. When that path passes near or over your location, you'll see a –8
dazzler. If not, you can use the map to drive to the sweet spot and 
await the
display.

The transition to the Iridium NEXT generation will be gradual but 
certain, so
make the most of the opportunities that remain. If you're a teacher, do your
homework and plan an outing to show a daytime flare to your science class.
Anything that gets people talking more about the sky is a good thing, and I
guarantee those kids will never forget the sight.
