Yes, I also saw quite a show.  I haven't followed Spot 3 at all closely, 
but last evening she was as wild as any but maybe C* 1933, C* 1953, DMSP 
F3, and SROSS-C2 in their best days.  She was quite bright, mag 2?, at her 
brightest during the limited period I saw her. 
 
Could your 12 s period be around 11.2 or 11.4 s?  There is some sort of 
11-something thing going on in the data below, but, at the margins, it 
gives me a shaky feeling, not as solid as I would like.  I hesitate to 
suggest that the 10.35 s between splits 2 and 5 below is a synodic 
anomoly, but it cannot readily be explained as a "bad squeeze" resulting 
in a long-short pair.  Regretably, I didn't have my tape recorder running, 
which would have allowed me to call out mags for the individual events. 
 
As in the case of 24871, I solicit suggestions about how to prepare this 
for PPAS.
