Observations 01 March 2005 Part 1 --------------------------------- Cosatrak 1 (Computerised satellite Tracking System). MINTRON low light level CCD surveillance camera (0.005 lux typical in non integration mode) and 0.00005 lux in STARLIGHT mode with 128 frame integration. Due to bright sky it is not worthwhile integrating more than 48 frames which is equivalent to an exposure of 0.96 seconds. Used with 145mm focal length f/2.5 lens giving a field of view of about 2.55 x 1.86 degrees and easily showing 12th magnitude stars. Not the best lens optically but the most useful in terms of field of view and magnitude penetration. Data recorded on DVD R/W disks - will be kept for 1 month and then re-used - just in case any queries as Im always making mistakes! Site 0433 : Longitude 18.51294 deg East, Latitude 33.94058 deg S, Elevation 10 metres - situated in Pinelands (Cape Town), South Africa ------------------------------------------------------------------------- Here is an update on the following previously reported as "High altitude unknowns" Object No 1: The following is still unknown but here are two additional observations found when I re-examined the same field taken several hours earlier 99999 00 000X 0433 G 20050301184532300 17 15 0826208+200354 39 99999 00 000X 0433 G 20050301184728500 17 15 0828155+200031 39 99999 00 000X 0433 G 20050301221827000 17 15 1155125+093222 39 99999 00 000X 0433 G 20050301221924500 17 15 1156058+092827 39 99999 00 000X 0433 G 20050301221946600 17 15 1156263+092651 39 99999 00 000X 0433 G 20050301222024100 17 15 1157052+092407 39 This object flashes irregularly to about mag +10.5 Object No 2 labelled "99998 00 000Y": Mike has identified this as Raduga 9, so here is the correct report plus two additional observations made from when I examined the field several hours earlier: 12618 81 069A 0433 G 20050301184612500 17 15 0825290+194334 39 12618 81 069A 0433 G 20050301184727400 17 15 0826467+194131 39 12618 81 069A 0433 G 20050301221835600 17 15 1157026+091300 39 12618 81 069A 0433 G 20050301221720000 17 15 1155501+091901 39 12618 81 069A 0433 G 20050301221950900 17 15 1158154+090807 39 Regularly flashes to about +7th mag, invisible in between. #28538 05004B NOSS 3-3 rocket: ------------------------------- Ted asked if I had a period for the magnitude variation. As best I could determine from the pass observed the period was between 5.0 and 5.1 seconds with a secondary maximum about in-between.
