In a local meeting Tristan Cools (TC) requested other satellite observers: Leo Barhorst (LB) and me (BD) to check all possible LEO Kosmos rockets. This is to detect possible re-tumbling in time. LB already reports his findings in his PPAS reports. From now on I report my findings in them too. To check possible variability I think one should follow the satellite along a rather large arc of the visible transit. Especially in the direction of the sun variability might be shown, but is difficult. I regard a satellite as "Steady" (abbreviated S) when there is no magnitude change other than caused by change in range and phase angle. The objects with a definite flash period are already in my PPAS reports. Here follow the others. 21231 1991-029B 2005-06-14 BD 34.1 s; 2005-06-15 LB 4.08 s!! 24773 1997-017B 2005-06-22 BD 46.2 s I found steady: the Kosmos-rockets in the 83° ~1000 km series: 07477 1974-079B 07737 1975-028B 09044 1976-077B 09638 1976-128B 10355 1977-087B 11586 1979-090B 11804 1980-039B 12836 1981-091B 13066 1982-012B may be it has an lp 14085 1983-048B 14966 1984-043B 15360 1984-109B 15598 1985-022B 16494 1986-005B 17240 1986-100B 17360 1987-009B 17526 1987-017B 18403 1987-087B 20150 1989-059B 21797 1991-081B 22488 1993-008B I found steady: the Kosmos-rockets in the 74° <~800 km series: 04071 1969-070B 04589 1970-086B 08344 1975-094B 08459 1975-112B 08924 1976-061B 10521 1977-119B 13992 1983-031B 19039 1988-029B 21015 1990-111B 22081 1992-053B More to check, also in other orbit-groups Bram Dorreman COSPAR 4160 51° 16' 45.5" N 5° 28' 36.6" E (WGS84) 35 m ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
