Observed my first (brighter than mag -4.5) predicted mag. -6.0 flare this 
morning on Dec 20 at 11:21:48 UT (06:21:48 local) with the Sun at -10.6 
degrees below the horizon. I was surprised it was as bright as it was 
since it was at a range of 1663 km and an elevation of 22 deg. The flare 
certainly peaked brighter than Venus (-4.7) and was easily naked eye 
visible for about 8 seconds with the peak lasting a couple of seconds.
