Correction of dates in the previous message (still getting used to 2020):

MGAB-V1111 = IPHAS J233843.55+571720.0
  20200113.1379   <166g   ASAS-SN
  20200113.9111   <195CV  COAST
  20200115.8762   <195CV  COAST  Last non-detection
  20200117.8429  15.64CV  COAST  Outburst!

AAVSO VSX entry (AUID requested, sequence requested, revision submitted):
https://www.aavso.org/vsx/index.php?view=detail.top&oid=1499458

As seen from ZTF light curve, the range is 15.2-21.1g and the normal
outburst was about 16.4. Thus, the current brightening is most likely a
superoutburst.
