Last night I observed two satellites in apparently similar orbits separated by just a few degrees. Both flared slightly between azimuth 265 and 270. Eventually I determined that they were #24967 and 25262.. Iridiums 36 and 51 respectively. On 4 Jun local (03:38:01 UT on 5 Jun) I observed another SV at RA 17:42.7 and DEC 51:49 (J2000). It was moving south to SE from the north. Using Alldat.tle and Skymap revealed no suitable matches. It seemed steady in magnitude (about 5-6th magnitude) during the short period I saw it. Realizing that getting only one data point is not the best for matching satellites, I made a better obs of an UNID on 6 Jun. I saw a naked-eye satellite occult Arcturus. Noting the time, I continued to follow it with binoculars until it passed a suitable star group near Polaris. Running Skymap and Alldat provided a perfect match.
