At 1997-10-12 08:08:07 UT I succeeded in my first attempt
to observe object 24869 1997-034 A Iridium 15 during
DAYTIME.
 
Randy John's program Skysat 0.4 was used to predict such a
potential daylight-satellite. The program computed for our
location the following data:
Time:     08:08:07    UT
Azimuth:       144    degrees (N = 0 degrees)
altitude:       79    degrees
distance:      803    km
Mirror 2:        0.11 degrees
 
The last value made me to try this transit at the predicted
location at the sky. We (my son Chris and I) were sitting
in armchairs using one-power. I counted down the seconds
(unfortunately too low, Chris could not hear me). At the
"moment supreme" I saw really a light dot about the expected
location, it lasted for only 1 second. Chris was just looking
at the clock and missed this special event. I feel sorry for
him.
It is difficult to give a brightness estimate. It was anyway
much brighter than Venus during daylight. We experienced
observing Venus during daytime many times (one-power).
 
Once more a prove that Randy's program is GREAT.
