 A follow up, ASAS-3 confirms the AB Nor outburst at around V=13.8 on
12.0664 2004 so now it may be near the end of the outburst. The last
outburst lasted around 12 days. If it is an analog to this outburst then
AB Nor is almost near the end of the outburst. However, rebrightening was
detected in AAVSO observations of that outburst and reported in the 2000
outburst in Kato's paper. So please try to follow it closely as it
declines. Since it is faint go unfiltered and stack images if appropriate.
The rebrightening may only be of a couple tenths of a magnitude if the
last AAVSO light curve is any hint:
