ASASSN-14cc (AM CVn star) https://www.aavso.org/vsx/index.php?view=detail.top&oid=398940
Apparently not much activity in recent months: after a normal outburst on 2021 May 23, the only recorded brightening was a double outburst on August 4-10 and 13-18, according to ASAS-SN Sky Patrol (Shappee et al. 2014ApJ...788...48S and Kochanek et al. 2017PASP..129j4502K) data. https://asas-sn.osu.edu/sky-patrol/coordinate/d031a323-285e-44df-9854-81a0e0...

Let's continue observations in the next season, too.

Title: ASASSN-14cc: Likely Helium Analog of RZ Leonis Minoris Authors: Taichi Kato (Kyoto U), Franz-Josef Hambsch (GEOS, BAV, Vereniging Voor Sterrenkunde), Berto Monard (Center for Backyard Astronomy Kleinkaroo) Categories: astro-ph.SR Comments: 5 pages, 5 figures, accepted for publication in PASJ (Letters) License: http://arxiv.org/licenses/nonexclusive-distrib/1.0/ \ We identified that ASASSN-14cc is a very active dwarf nova spending approximately 60% of the time in outburst. Our long-term photometry revealed that the object shows long outbursts recurring with a period of 21-33 d and very brief short outbursts lasting less than 1 d. The maximum decline rate exceeds 2.8 mag/d. The duration of long outbursts is 9-18 d, comprising 50-60% of the recurrence time of long outbursts. We detected 0.01560-0.01562 d (22.5 min) modulations during long outbursts, which we identified to be superhumps. These features indicate that ASASSN-14cc has outburst parameters very similar to the extreme dwarf nova RZ LMi but with a much shorter superhump period. All the observations can be naturally understood considering that this object is a helium analog (AM CVn-type object) of RZ LMi. The highest outburst activity among AM CVn-type objects can be understood as the high-mass transfer rate expected for the orbital period giving a condition close to the stability limit of the accretion disk. In contrast to RZ LMi, this object shows little evidence for premature quenching of the superoutburst, which has been proposed to explain the unusual outburst parameters in RZ LMi.
