At the beginning of the new year i saw Iridium 27 'strobe' on near-zenith
passes and on successive nights i was able to observe it. It's rate of
flashes were varied, some were at -3 to -4 while others were barely visible.
Some times i could only pick it up as it was directly above while other
times i would see it coming up from the south, although only once it got to
about 40 dgrees. As it decended to the north i could track it until it got
to about 20 degrees. I had hoped to see it again as it came into view once
again recently but the skies up here didn't get dark enough to see it.
