	I also saw this.  However, I figured it to have a 8-9 second
period between the invisible minima.  The pattern was like this:
	inv --> +0 --> +3 --> +1.5? --> +3 --> +0 --> inv
The +1.5? was a very quick flash during the +3 minima.  All I can really
say is that it wasn't as bright as the main +0 flashes.
 
	The other two satellites I observed, Iridium 70 delta rocket
(98-32F, 25374) and Cosmos 1943 rocket (88-39B, 19120), were both steady,
and both in the +2.5-+3.5 range.  The Iridium 70 rocket really zipped
across the sky, crossing in about 3 minutes.
