                 Flash email report for April 1995

Some history

The Belgian Working Group Satellites (BWGS) has been active in collecting flash
period observations of artificial satellites since 1987. All observations
are part of the PPAS database (Photometric Periods of Artificial Satellites)
which now contains over 34000 observations from more than 1200 satellites.
The Working Group publishes a monthly newsletter Flash, which is open to
contributions by observers (about any kind of satellite observations).
This email report is an addition to the newsletter. We welcome all observers
to send their flash timings to or BWGS,
Bart De Pontieu, MPE, Giessenbachstrasse, D-85740 Garching, Germany.

SATORAMA (by Tristan Cools)

Our observing programme can be found in part 2.
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

Special remarks

70-106B: beginners object now but we need more regular obs !
75- 27E: flashes confirmed by BD & KJ
75-105A: Molniya 3-03: flashes seen by Daniel Laszlo
77- 79J: to be checked if something happened
78- 42A: could become extremely bright
79- 50A: to be followed more regulary
82- 55B: deleted because steady
82- 69B: same as above
83- 31B: flat maxima
83- 99A: prototype Okean satellite, seen flashing by RE
83-108B: last observations hp ?
85- 23J: still to be followed closely
86- 30B: deleted, steady
86- 39B: deleted, steady
86- 86B: deleted, steady
86-100B: new flasher seen by Willy Verhaeghen
88- 50A: = Kosmos 1953, discovered by Walter Nissen
88- 06A: out of order; nice flashes seen by TC
90- 83B: C1 Kosmos 2100: new, varying acc to JP Rohart
92- 36B: jumped into the programme again
92- 42G: new, variations seen by RO
94- 57D: deleted because invisible
94- 66B: deleted because S
94- 68B: seen flashing by TC, difficult
94- 74B: to be observed at low elevations->flashing
94- 85B: flashing or not flashing ?  not very convincing
94- 86G: S so deleted
95- 08B: C1 Kosmos 2306: probably flashing
95- 12B: C1 Kosmos 2310: probably flashing

Top-priority objects

65- 08A: accelerating, triple maxima
79- 30B: small accelerations
83- 01B: going down or hp ?
84-109B:global decrease
85- 11B: going down ?
85- 41B: accelerating !
85- 94G: Tsyklon wich is accelerating-exceptional
85-116B: sudden acceleration confirmed by LB
86- 02J: last obs S
86- 37B: complex acceleration curve
86- 93B: flashing or S ?
87- 49B: accelerated acc to BD, MM and RO
87- 51J: acceleration seen by Leo Barhorst !
88-102A: short period now ?
89- 28B: dtm ?
90- 04B: accelerated again, seen by BD
90- 36B: ssm
90-111B: seen with short period by BD
91- 19B: short period seen by BD, DC and TC !
91- 59B: many sm->hp
92- 08B: going down
92- 12B: short period
92- 20B: probably going down
92- 38A: ID reversed with 38B ?  Scout rocket now ?
93- 01B: new acceleration
93- 36B: 5 seconds again ?
94- 24B: accelerated and still going down
94- 45B: slightly going down again ?
