My apologies if this is not the place to pose this question.
I observed what appeared to be a fairly bright satellite travelling
towards the western horizon at a slight N-S angle (i.e., mostly
vertically going down E to W), with regular, smooth brightness
variations with roughly a ten second peak-to-peak period (as my memory
This was roughly at 0019 UT on 4/9, from Evanston Illinois (42.04 N,
87.68W), at a rough initial azimuth of 265 degrees and elevation of
about 20 degrees.
There were several jets passing through the same area of the sky, and
they all displayed extended contrails with no specular brightness
Does anyone know of any candidates for what this might have been?
Thanks in advance.
