Observed what must be the Zenit, at about +2 when it first appeared.
There were three or possibly four one-power maxima in about 20-40
seconds, each one significantly fainter than the previous, due to
deteriorating phase angle and increasing range. It was one-power
invisible between the maxima. Here's the Quicksat output:
