	I watched these as well last night.  It was our first clear
(no clouds whatsoever) night since our deluge last weekend.

	I observed two sets of three flashes followed by a set of four
flashes.  The middle flash was brightest of each set.  I'd say the flashes
were on the order of -1, -3, -1 with the last set having an extra trailing
-1.

	I found that the flashes before culmination were irregularly
spaced, or at least I didn't discern on obvious period.  After culmination
I saw four sharp, very bright flashes spaced about 5s apart; all four
appeared to be Venus-like (>= ~-4).

	This one was a +0 flare for me.  Made for a nice sight as it
flared through the "M" of Cassiopeia.
