Night sky viewing coming up—ISS, Comets, Flares and a Spy Shuttle



There's a stack to look at in the sky during the first half of March. First there's the Comet C/2011 L4, also known as PANSTARRS. This lovely photo was taken by Canberra Astronomical Society member Vello Tabur on 5 March. Look just south of where the sun goes does, immediately after sunset. No scope required, but a pair of binoculars will make your viewing a little more enjoyable. It's getting closer to the Sun so won't be visible for much longer.

There are a few really bright Iridium flares, short extremely bright bursts of reflected sunlight off satellite telephone satellites:
