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.
