I interpret your text as saying "something culminating near azimuth 225 and moving near az 195 alt 25, heading to horizon near az 135", and find nothing matching. In general, and in particular when only a short arc is observed, or it is observed through binoculars, it is more useful to estimate the track's local angle relative to the vertical, or to a pair of stars in the field of view. An apparent speed is also helpful. In Henney2.gif, Cosmos 1104 moves in dir=215 approximately, and Cosmos 654 in about 235 degrees. Both are "too late". Do they fit ? If you have a graphic tool like SkyMap or ObsReduce, you can read the cursor alt/az or RA/Dec (in SkyMap) or mark a star and a distance and direction from it and read them from the screen or a log file (in ObsReduce). With one point in RA/Dec, you can use IdSat to get matching suggestions, but two points give a mutch safer ID, using a graphic prediction tool or even an orbit determination program. > 20:50 hrs UT (approx) Sheffield UK 53.3830N, 1.4660W +220M OD > saw a slow flasher, period about 3 seconds maxima about > +1, fading to invisible, 2nd maxima about +3 > Moving NW - SE through Scutum area.
