Hi all,

While scanning for NOSS 5 C on the 9th & 10th, I came across five UnIds
That I've subsequently Id'd.  Two were GREB Rk and Cosmos 1447. What is
GREB rk or
What is GREB an acronym for?
Cosmos 1447 was rotating with a 2-3 sec period estimated.

 As Ed mentioned in his recent posting the 9th was one of the coldest
nights I've spent Outside at 20 degrees. The light breeze probably
dropped
the wind chill to around 5-10.

Staying warm
