V3101 Cyg: another superoutburst during the rebrightening phase

Itoh-san and Maeda-san reported further observations of V3101 Cyg.

Time-resolved photometry on 26th Dec. with the baseline of ~5hrs by
Itoh-san showed possible growing superhumps.

This object experienced the last superoutburst in rebrightening in March -
April, and slowly has been decayed until this another rebrighening.
Considering the peak magnitude and detection of possible superhumps, this
rebrightening is likely another superoutburst during the rebrightening
phase (Totally 7th rebrightening and 4th superoutburst during the
rebrightening phase).

Time-resolved photometry is encouraged!

Best regards and have a nice holiday!
