Hello,  

Last weekend I had a good all night observation session.  Again we 
were able to see 4 Astra's in one eyepiece of a 22cm Dobson.

I also saw the negative flashes of 93- 50 A (NOAA 13): a first one to -2,
followed by one to mag 0 and then becoming invisible for the naked eye. 

I already received a lot of observations so I was able to compile a 
preliminary report of some interesting objects:

=18586  It seems that the period of this Cosmos 1898 rocket is still 
going down.

First observations after jump in Mean Motion.  Is it still accelerating?
Obs of this object are needed urgently.  It is visible for Northern
latitudes!

This one had a small MM jump in the beginning of April.  I saw it flashing
clearly, but with a high period.  We need more observation to confirm this.

This last observation of Leo might indicate that this object is
accelerating although there is no jump in Mean Motion.

These observations clearly show the acceleration part.
