[vsnet-alert 15035] Re: MASTER OT J054317.95+093114.8 rapidly fading

[Josch Hambsch]

Hi,

I have not been able to detect this object any more on my images, even after 
adding two or four images up.

The magnitude must be well below 18 mag.

Regards,
Groeten,
Grüße,

Josch

After 3 weeks of slow fading at nearly the constant rate of 0.12
mag/day, this variable has finally dropped by 1.7 mag in 2 days, as
shown by the observations with MASTER-Amur 0.4-m f/2.5 telescope
(60-sec exposures, unfiltered magnitudes with USNO-B1.0 red zero
point):

MASTER OT J054317.95+093114.8

  20120930.785  134C  MASTER-Amur
  20121017.773  155C  MASTER-Amur
  20121017.784  156C  MASTER-Amur
  20121019.710  158C  MASTER-Amur
  20121019.721  158C  MASTER-Amur
  20121021.709  175C  MASTER-Amur

The nightly monitoring is now strongly desirable, especially for the
whole next week, to see if the variable will show the rebrightenings
which are the main distinguishing feature of UGWZ-type dwarf novae.
