Every so often I need a cloudy night to catch up.

First the flashers:

The Mir has made some nice passes this week. It was -2.5 mag as it passed 
under Mars/Spica on 16 May 01:29 UTC and 1.0 as it passed over Mars/Spica 
(145az, 32el) on a twilight pass on 18 May 00:49.

Speaking of space stations...
The recent delay of the ISS docking mission by 1 week to 27 May had the 
effect of creating some visible passes during the STS-96 mission for the 
eastern USA.  The bad news is that they are all predawn passes.

Fengyun 1C r (25732) seems to sparkle occasionally to a +4.0 and is flashing 
too.

UARS (21701) has also been making some bright passes.  Last evening it flared 
to a --1.5 mag for about 10 seconds.  The center time was 01:23:17 UTC 18 
May.  Otherwise it was a +2.0 mag. 

My favorite fragment, Spot 1 r BJ (17206), made an unusual pass in that it 
was 1x at +3.0 mag and the brightness variation were difficult to observe 
(75az, 65el; 02:27:30 UTC 18 May).  Normally it tumbles at a 3 second period 
at +4.0->inv.
