while looking for a sat last night, I did
not see it and Guide8 (and some other apps)
predicted it should be +6.6 an easy see with
my scope in a +10 moonless sky. but sat no show
so that's how I reported it, missing, but reply
was that my mag data was wrong, and that the
sat was probably +8.. LEO sats in that +8 range are
rarely seen by me although I may see stars at
+10.2. so the question is, how is sat mag data
updated, can user update it, etc.
