The first four lines were reported in [vsnet-alert 24045].
The current outburst is too long for a normal outburst. Duration of ~10
days is rather normal for a superoutburst. The current behavior is too
strange for a superoutburst, either. The fading rate during the Dec. 2008 -
Jan. 2009 superoutburst was about 0.1-0.15 mag/day - typical for UGSU.
2008/2009 superoutbutst has peaked at 12.7V fading to 14.5V in 12 days.
March 2020 outburst was fainter by 0.7m in the beginning, but is brighter
by 0.6m at T0+8 days.
Has anybody obtained a 2-3 hr long time series during the last week? Have
been the superhumps detected?
P.S. AAVSO observer FJQ has resubmitted his measurements of AQ Eri. AAVSO
light curve generator is giving the correct data now.
