[I received the following message from Kurt Jonckheere to be
posted to the list.  Mike McCants]

hello all,

in the next days, I will prepare the first update to the PPAS 8,
our database of measurements of the flashing period of all
objects with varying light curve.

Especially if you still have observations of 1998, please send
them as soon as possible, because somewhere in March I
will make the report of '98.

All observations are appreciated very much !!

Some more info below :

The Belgian Working Group Satellites has been collecting observations of 
flashing periods for several years now.
As different people can report the same thing in different ways, the best
is to collect observations in a standardized way.  Therefor the PPAS
format was created.
PPAS = A database collecting Photometric Periods of Artificial Satellites.

The PPAS format looks like :
Cospar   Date     time UT    ob total acc  #of flash  remarks
ID       YY-MM-DD HH:MM:SS.s se time       fls period
94- 56 A 98-04-14 12:06      AB  193.7 .04  10 19.374 +-.004, flsh peak mag +2

Thanks to this standardization, it is easier to create an archive and
to start with analyzing the data.

We have provided a e-mail address to which you can send your observations.

In this way you make sure your observations are collected and made available
for everybody for analysis.
Please send your observations of flashing satellites, preferrably in the 
correct PPAS format to ppas@lists.satellite.eu.org

If you send your observations to SeeSat-L, please also send a copy to the
observations address.  In this way you are sure your observations will be
used for the updates to our PPAS archive.

You can find more information about the Belgian Working Group Satellites
and our PPAS archive starting from :
http://www2.plasma.mpe-garching.mpg.de/sat/satintro.html
and looking for BWGS and PPAS.

If you have any questions about the above or you want more information,
do not hesitate to contact me !

Greetings,

Kurt Jonckheere, observations collector for the Belgian Working Group Satellites.
