Observations 28 May 1997    (Wed Eve., 29 May UT)

05:36:57 UT Unexpected satellite seen moving through northern
            Virgo into Serpens Caput, Mag. 4. Probably
            Cosmos 1867 (#18187). Predicted mag by Skymap
            using Molczan standard mag = 4.5.

05:57:11.   First observed flash from geosync flasher
            Gorizont-23, #21533. Time of
            observation was selected randomly, to match when it
            passed near some bright stars. This is approx 1 hour later,
            local time, than my previous observation. Mag of flash approx
            5 to 5.5, duration approx .5 sec. Timed 15 flash periods
            in 13 mins 20.6 seconds, for a period of 53.37 seconds.
            Previous determination on 25 May was 53.36, using fewer
            periods; this value is probably more accurate.

            This reconfirms the supposition that this geosync
            flasher flashes ALL the time.
