ISS To Become Second Brightest-Object In the Sky
Matt_dk writes "Move over, Morning Star. Once Canadarm2 helps install the fourth and final set of solar array wings to the International Space Station later this month, the Station will surpass Venus as the brightest object in the night sky, second only to the Moon. The Space Shuttle Discovery is set to deliver the power-generating solar panels and Starboard 6 (S6) truss segment to the ISS on the 125th mission in the Shuttle program, known as STS-119/15A (slated for launch on March 11)."
Yes, the ISS is bright and will be brighter.
This still doesn't rival the brightness of an Iridium flare.

Then there have been comets and supernova that have been visible during daylight. Yea, I think the ISS is cool to observe, but don't call it 2nd brightest after the moon.
It could be worse, it could be Monday.
