Last night the clouds finally cleared & I had my first chance to observe Gorizont 23. I initially aquired it in 10x50 binoculars & then watched more closely with my 6" newtonian telescope between 21:45 & 22:15. Unfortunately, I didn't think to make any accurate flash period measurements. The only timing I took was over two flashes & gave a period of 50s. Each flash lasted about 1s & reached c.a. 6th Mag. If the weather clears up again I'll have a go at making a more accurate timing for the people who can make use of these flash measurments. When I was searching for Gorizont 23 with binoculars I spotted a flashing object in the correct area which initially took for Gorizont. However, subsequently after observing Gorizont for a while in the telescope I realised that what I had initially saw couldn't have been Gorizont. It flashed irregularly up to 5-6th Mag with 5-10s between flashes & showed slow, but perceptable motion to the east in binoculars (perhaps 1 deg / minute). Unfortunately I didn't note the time (thinking I was seeing Gorizont), but the observation must of been between 21:30 & 21:35 UT, 25-Feb-98. The object moved on a trajectory roughly parallel & about 1deg S. of 23 Mon & zeta-Mon. (ie. in the same area where Gorizont was at the time) Anybody any ideas what this might be? Sorry for the lack of precision in these obs. - at the time I was only planning on just trying to find Gorizont (in fact I was planning on an early night before the sky cleared!).
