For tumbling/flashing satellites, see the Observing Program of the BWGS:

especially the ones marked "b" or "!".

For the three brightest trios/triplets, get the Molczan file (available
from several sites) or classfd.tle, which is available as a zipped file

and look for the ones named NOSS 2-1, 2-2, or 2-3 (1990-50 C, D, and E; 
1991-76 C, D, and E; and 1996-29 C, D, and E [hoping I've got the object
letters correct]).  Those are the three brightest threesomes, sometimes 
reaching one-power magnitude in reasonably good sky and occasionally -- 
according to reports -- flaring even brighter.  The earlier NOSS trios
are much fainter objects, and some of those triangles have "fallen

Also very interesting are USA 32 (19460, 88-78A) and USA 81 (21949, 
92-23A), which sparkle brightly on good passes.  Here's a description of 
them that Mike McCants wrote a while back:

TiPS is about it for this category right now:

Anytime there's a tethered satellite, you'll hear about it!

Someone else will have to provide this list.  Some geosynch and near-geo
satellites are on the BWGS list of tumbling/flashing objects.  See also
> Is there a ongoing SeeSat Hall of Fame list?

I don't think so, although a quick scan of the Visual Satellite
Home Page: (The "2" is

hits some highlights:  bright satellites, flashing satellites, Centaur 
rocket boosters, geostationary, ISS, Iridium, Mir, re-entering
and spy satellites.

By the way, I hope you've seen EGP....
