OGLE-MC-DN-0008 (UG) https://www.aavso.org/vsx/index.php?view=detail.top&oid=478014
I just had a look at the latest ASAS-SN Sky Patrol data for OGLE-MC-DN-0008 and noticed that this dwarf nova is undergoing a rare outburst (which started on Oct. 17 or 18): https://asas-sn.osu.edu/sky-patrol/coordinate/d946ac58-407a-41d0-888f-842dbb...
Time-resolved photometry is urgently required.
