Hello everyone, I have been almost one year without observing satellites because I bought a webcam and so I could make images of Jupiter (observing this planet has been my first astronomical interest...for 40 years!). But now, Jupiter has gone and I am ready to make new observations of satellites, particularly geoflashers. Recently, as clear skies have come back, I mad some interesting observations : GORIZONT 23 (21533U 91046A) : - I saw it on 12 May with my C8, very faint : 91- 46 A 01-05-12 23:15 MJ 714.9 0.2 23 26.42 F'aF'; mag 12-13,sp - last Friday, Saturday, Sunday and Monday, I did not see it, although the sky was very clear and no moon TDF 2 ( 20705U 90063A) : 90- 63 A 01-05-19 23:00 MJ 436.6 0.5 20 21.8 very bright flashes at the beginning of the observation (about mag 5) then the maximum decreased to mag 10 OLYMPUS 1 (20122U 89053A) : 89- 53 A 01-05-20 00:02 MJ 1356.1 2.3 9150 secondary max 40 s. after max COSMOS 2172 (21789 91-79A) : seems to have an assymetrical period : 78.6 (standard deviation = 1.3) and 72.6 (standard deviation = 1.3) Here are my measures (in seconds): 78.98 73.00 77.66 74.62 77.18 72.98 78.18 72.32 80.93 70.59 79.20 72.40 GORIZONT 8 (14532 83118A ) : 83-118 A 01-05-21 21:26 MJ 426.1 0.7 12 35.5 A'A' short flashes All these observations have been made with a C8 and thanks to Rob's Skymap which is such a precious tool!
