As Ed Cannon mentioned in an earlier email, we had a very nice pass of ISS over Austin last night (1999-02-24 01:27 UTC). Peak magnitude was about -1.5. The really interesting thing about this pass was the brilliant blue color. ISS was a very easily distinguishable whitish-blue color just before and just after culmination, which slowly faded to bluish-white, then finally to white, after culmination. ISS was moving roughly west-southwest to north-northeast, culminating at 62 degrees in the northwest. The sun elevation was about -14 deg. Here's the QuickSat output for this pass: ------------------------------------------------------------------------ 30.321 97.773 1000.
