A week ago Mike McCants and I observed Gorizont 14, and using Mike's 8-inch telescope I got half-period times during an observing session of 03:30:37 to 03:52:36, 24 January UTC. The secondary maxima were fainter. Then last night and this morning off and on over about six hours, 3:44:33 to 9:43:21 Jan 30 UTC, I observed it several times using binoculars. During the last sub-session only, beginning at 9:30:31 (3:30 a.m. local time), I saw a few secondary or half-period flashes. A few of these flashes (primary and secondary) were bright enough that I thought that if I'd been at a good site, they might have been visible at one-power.
