I'm back from two weeks holidays with only a few observations.  I 
observed the NOSS-cluster by coincidence and could made some 
observations for the DRA-Project.
Unfortenately, because I had no access to the Net I didn't know
about the Titan IV.

For the newbies :  DRA stands for Determination of the Rotation 
Axis of a flashing satellites.  This is done by making as many
as possible timings of the flashes of the rotating rocket.

I could make some observations of 92- 12 B and 95- 32 B, both 
objects being in the DRA-list.  All observers should try to 
catch up these rockets, because the more timings we (Bart) 
receive the better (more accurate) our results will be.

Now that I'm back, I can also create the next update of our
database of Photometric Periods of Artificial Satellites,
PPAS.  This database already contains more than 30000 flash

 Please send your observations preferably in the correct format 
 before Sunday evening July 21.

You can find more information about the PPAS via our web-pages:
or you can drop me a mail.  In return I can send you a description
of the correct PPAS-format or other information you need.

Even if you are very new to making flash observation, don't
hesitate to send us your flash period timings, every observation
is valuable !

Happy observing,

Kurt J (observations collector)
