Under clear but cold skies i was able to observe Irid 11A S/D #25580 and
Iridium 11A r #25579 as they sped across the sky.

As i was tracking Iridium 11A r as it headed south, i noticed a -4 magnitude
glint about 5-10 degrees east of it at 00:37:40 at about 60 degrees. At
first i thought it may have been a tumbling Iridium but then i remembered
that Gblstr 1 Dlt r #25166 was due to pass by at that time and checking
later on, it matched the track of the glint.

I was also able to observe ISS #25544, as it passed directly in front of
Saturn and as it continued on towards the east it's magnitude increased
until it matched Saturn. I was able to follow ISS until just before it
reached Orion when it faded out of sight. Other objects seen were, (all
times UTC 06 Jan 99):

Meteor 1-29 r #11252 00:40:56 
Cosmos 1063 r #11156 00:43:29 
Cosmos 807 r  #08745 00:59:21
