This is my first time viewing this object and suspect it does not get
observed very often. Quicksat output and 2-line elements are below.
Considered a high object, but does get low to the ground at perigee
(300km). It just happened to be making a favorable pass in the north. In
addition, we had a cold front move in from Canada to cool things off and
clear out the haze and humidity. Went to OIG to get the latest elements, to
reduce the time of uncertainty to .1 min, was over a minute. It came on
time, moving fairly rapid among the stars with smooth brightness variations
of mag 5.5 to 7 with a 1 sec period.
