Caption:
October 8, 2017 - A magnitude -4 Iridium satellite flare descending toward the northern horizon, shot in southern Alberta, Canada. There are numerous other satellite trails in the frame and at least one aircraft. While predicted to be -7, this flare was more like -4 at best. But the satellite was visible before and after the flare. This was Iridium #13.. The glow in the clouds is from Drumheller to the north.
