I just watched Columbia's night launch from my backyard in Orlando (I realize 
the ambiguity of that statement, but rest assured, the -launch- was from KSC 
;)). The orange tail from the solid rocket boosters was clearly visible from 
~10 degrees above local horizon to ~25 degrees when the glow gradually 
changed to blue/white. At separation, the SRB's appeared as two dim red spots 
(much like automobile tail lights) forming a (roughly) isosceles triangle 
with the main engines. The SRB glow faded out for a few seconds (tumble?) 
before reappearing and finally fading out. The white glow of the main engines 
gradually appeared to shrink and descend towards ~20 degrees. Unfortunately, 
the humid night caused the diminishing 'star' to fade out ~40 seconds before 
Main Engine Cut Off (MECO).

STS-93 was launched 7 minutes later than the nominal 04:24:00 at 04:31:00.

Here's looking forward to observations of STS-93 and Chandra (the largest 
object delivered by STS so far).

Godspeed Columbia
