SDSS J141118.31+481257.6 rebrightening - photometry requested
Active Dates: June 1, 2018 – June 1, 2018
Abstract:
Further to AAVSO Alert Notice 635, the AMCVn binary SDSS J141118.31+481257.6 is rebrightening, and the expected superoutburst may be underway.
Justification:
As predicted the object started to brighten again. Last night [May 31/Jun 1] we found it at 16mag and quickly rising with ZTF. I expect that it will now go into a superoutburst phase where it stays very bright for a few weeks. During that phase we are expected to see superhumps in the accretion disc which show a period which is slightly different than the orbital period (46min for this system) and are powerful to learn about the mass ratio and accretion discs in general.
