Re: EI UMa: bright outbursts recently

ASAS-SN data: https://asas-sn.osu.edu/sky-patrol/coordinate/cfa667b6-c1a4-4af8-8288-cddff4...

It appears that the outburst mode has changed since 2019 Sep. ASAS-SN show more outbursts with smaller amplitudes and I found a mean period of 56.4 d (which had not been detected by Reimer et al. (2008) ApJ 678, 376). The M_V of these outbursts were +3.6 at peak and look compatible with dwarf nova outbursts. Brighter multiple peaks with shorter durations reaching g=12.5 have M_V = +2.2 and they are not considered to be dwarf nova outbursts (support for IP outbursts).
