> Pierre Neirinck reports that USA 129 was on time for his first pass of the > evening. > I've had 99% clouds every evening for a week, and not seen USA 129 since Apr 08. At a few previous manoeuvre instances that I checked, the KH's raised their orbits at a perigee pass immediately after the southbound pass closest to Vandenberg (or the KH control center E thereof). The perigee is now just N of the equator, and the manoeuvre could have been done on Apr.17 at 17:08, possibly 18:45, had not Pierre reported the on-time pass. On Apr.18 this is 17:24 UTC, possibly 19:01. When the apogee has been raised, MM should be around 14.76, so it would be about 8 minutes late per day. On the first pass over central Europe, it would be about one minute late, over eastern USA about 3 minutes late, and over California 4 minutes. The eccentricity would be around .0503, so the height at mid-northern visibility would be around 40 km higher than now. This means that on a pass in the east, it will be considerably higher in altitude, but in the west it may be higher or lower, depending on the lateness. -- bjorn.gimle@tietotech.se (office) -- -- b_gimle@algonet.se (home) http://www.algonet.se/~b_gimle -- -- COSPAR 5919, MALMA, 59.2615 N, 18.6206 E, 33 m -- -- COSPAR 5918, HAMMARBY, 59.2985 N, 18.1045 E, 44 m -- -- SeeSat-L / Visual Satellite Observer Home Page found at -- -- http://www2.satellite.eu.org/satintro.html -- ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www2.satellite.eu.org/seesat/seesatindex.html
