Observing Program of the BWGS ----------------------------- The Belgian Working Group Satellites has been active in collecting flash period measurements since 1987. Our priority list contains over 300 satellites.

SATORAMA Our observing programme can be found in the Program.rob file. It is subdivided in categories, the codes of which can be found below. b flashing object for beginners d difficult to measure S steady object, potentially flashing in the future ? flash period is unknown or uncertain - long flash period (>40 s) ! top-priority object regular object x DRA object Special remarks New objects : Some time ago, Paul Maley pointed his telescope to a number of Ariane rockets and derived flashing periods from the light curves of them. Most of these objects were never observed before, which explaines the following long list of new objects: 60- 9 B d 50/Delta 1 R/B, NEW, discovered by Vince Gardiner, faint 65-109 F d NEW, discovered by LB, secundary maxima 79- 87 C 17939/SL-12 R/B, NEW, geosat. discovered by Jay Respler 88-109 C 19689,Ariane 44LP R/B, NEW discovered by Paul Maley, GTO 89- 62 C d 20170/Ariane 44LP R/B, NEW discovered by Paul Maley, GTO 89- 87 B d 20316/Ariane 44L R/B, NEW discovered by Paul Maley, GTO 90- 63 C d 20717/Ariane 44L R/B, NEW discovered by Paul Maley, GTO 90- 91 C d 20874/Ariane 44L deb, NEW discovered by Paul Maley, GTO 90-100 C d 20947/Ariane 42P R/B, NEW discovered by Paul Maley, GTO 91- 15 C - 21141/Ariane 44LP R/B, NEW discovered by Paul Maley, GTO 91- 26 B d 21223/Ariane 44LP R/B, NEW rediscovered by Paul Maley, GTO 91- 55 B d 21654/Ariane 44L R/B, NEW discovered by Paul Maley, GTO 91- 67 B d 21727/Ariane 44P R/B, NEW discovered by Paul Maley, GTO 92- 41 C d 22032/Ariane 44L R/B, NEW discovered by Paul Maley, GTO 92- 84 B d 22254/Ariane 42P R/B, NEW discovered by Paul Maley, GTO 93- 48 C d 22725/Ariane 44L R/B, NEW discovered by Paul Maley, GTO 93- 61 A b 22823/SPOT 3, secundary maxima!, bright flasher, NEW 93- 73 C d 22913/Ariane 44LP R/B, NEW discovered by Paul Maley, GTO 94- 38 E 23172/SL-12 R/B (AUX MOTOR)NEW, discovered by Jay Respler, GTO 94- 49 C d 23201/Ariane R/B, NEW discovered by Paul Maley, GTO 95- 2 A 23463/Tsikada, NEW, discovered by Eero Rantalaiho 95- 29 B d 23599/Ariane 42 P R/B, NEW discovered by Paul Maley, GTO 95- 40 B d 23637/Ariane 42L R/B, NEW discovered by Paul Maley, GTO 95- 55 B d 23687/Ariane 42L R/B, NEW discovered by Paul Maley, GTO 95- 67 B d 237/Ariane 44L R/B, NEW discovered by Paul Maley, GTO 96- 2 C d 23766/Ariane 44L R/B, NEW discovered by Paul Maley, GTO 96- 7 B d 23782/Ariane 44P R/B, NEW discovered by Paul Maley, GTO 96- 15 B d 23817/Ariane 44P R/B, NEW discovered by Paul Maley, GTO 96- 22 B d 23847/Ariane 42P R/B, NEW discovered by Paul Maley, GTO 96- 30 C d 23866/Ariane 44L R/B, NEW discovered by Paul Maley, GTO 96- 44 C d 24210/Ariane 44L R/B, NEW discovered by Paul Maley, GTO 96- 63 C d 24654/Ariane 44L R/B, NEW discovered by Paul Maley, GTO 96- 72 A USA 129/NEW 97- 6 D 24728/C 2337, NEW, variable according to Leo Barhorst 97- 6 E 24729/C 2338, NEW, variable according to Leo Barhorst 97- 10 B 24745/post boot stage NEW, flashing with 17 seconds (LB) 97- 17 B b 24773/C 2341 R, NEW, nicely flashing according to Leo Barhorst Top-priority objects : 84- 56 B ! 15032/C1 Kosmos 1570: accelerated according to Leo 85- 94 G ! 16144/F2 Tsyklon K1690-1695, accelerated ? 87- 6 B ! 17304/C1 K1814; MMJUMP !? 87- 49 B ! 18096/C1 Kosmos 1850: accelerating again ! 87- 60 A ! 18187/Cosmos 1867; still accelerating 87- 74 G ! 18340/F2 Tsyklon Kosmos 1875-1880: acceleration halted ? 88- 53 B ! 19257/C1 Kosmos 1954: still accelerating 92- 20 B ! 21938/C1 Kosmos 2184: period going down ?, MMjump in Mar 97 93- 15 B ! 22564/Centaur UHF1: GTO, flashing, period going down ? 93- 70 B ! 22889/C1 Kosmos 2266: MMjump, also accelerated ? 94- 41 B !x 23180/C1 Nadezhda 4: going down ? 96- 4 B ! 23774/C1 K2327: Accelerated during Jan 97 ! 734 observations received from : ANO: Antero Olkkonen, Ristuna, Finland BD: Bram Dorreman, Achel, Belgium ER: Eero Rantalaiho, Virkkala, Finland JHR: Jay Respler, Freehold, NJ, USA JVS: Jan Vansteelandt, Leuven, Belgium KJ: Kurt Jonckheere, Antwerp, Belgium LW: Leo Wikholm, Helsinki, Finland LB: Leo Barhorst, Alkmaar, The Netherlands PM: Paul Maley, Houston TX, USA RE: Russell Eberst, Edinburgh, Scotland TC: Tristan Cools, Brugge, Belgium RGL: Ron Lee, USA VAG: Vince Gardiner, Coffs Harbour, Australia Next deadline for sending in observations: June 10, 1997 to Kurt Jonckheere Sanderusstraat 15, bus 3, B-2018 Antwerpen, Belgium or by e-mail to ppas@cds.plasma.mpe-garching.mpg.de All observations are appreciated very much. If you send your observations to Seesat-L, please also send them DIRECTLY to ppas@cds.plasma.mpe-garching.mpg.de. This is just a small amount of additional work for you, but it makes live much easier for me. Happy observing, Kurt Jonckheere (kjonckheere@unicall.be) Observations collector of the Belgian Working Group Satellites
