"Wildly" is a very good description.  I've made several obs of Spot 3 over 
the past few weeks.  On the evening of 12 April (circa 01:30 UTC 13 April) 
the primary flashes were still about 13 seconds apart but there were regular 
secondary flashes.  Two just before the main flash, one abot 6 secs after the 
main flash.  It was a relatively low elevation pass in the NE sky.

On the evening of 14 April (at 02:39 UTC 15 April) the main flash seemed to 
increase in brightness slowly, then suddenly flash.  This was a high 
elevation pass (340az, 60el) descending to the horizon.   

Spot 3 is definitely an interesting object for the Northern hemisphere 
observers to see this summer.
