Jim varney in his message sat's "Beautiful night last night", he send his
message on the june 15, so correcting for time zones, he observed the noss
7 cluster on june 14. He say's he observed a satellite of around mag 7,
which there was a pass of the noss cluster, of mag 7 on that night. Looking
at the orbit of the noss 7 cluster, the D member of noss 7 leads the other
two members. The D member is ahead of the other two that by doing a scan
around it, you won't notice the other two members of the cluster unless,
you happen to look back around 20 degrees in which you would see the E
member following close to the same track across the sky as D. The members E
and H are close together, that if you were looking at E, then moved your
binocular's in the direction of where H is, you would spot it. Since jim
only saw one,it should have to be D memeber because it is far ahead of the
other two, and thus fit's the description of only seeing one satellite,
even after doing a scan around it because of the distance between D and the
E/H memebers. The noss 7 cluster would have made a mag 7 pass on June 15 at
around 5:42 UT, so subtracting the local time zone difference, the pass
would have taken place the on Jun 14, for jim, the night jim was observing.
If this is wrong jim what time and date did you observe?
