> Observations using the Faulkes Telescope between 2009 Oct 12 13:43-14:27 
> UT
> show that the star continues to fade at a faster rate than that reported 
> by
> Ian Miller.  17 x 40 sec V(Green)- filter images show a very clear decline
> from V=15.02 to V=15.10 (+/-0.01 mag) during this time interval.  A linear
> fit to the data gives a fade rate of 2.6 +/- 0.4 mag/day.  There is some
> evidence that the rate of decline is slowing.  Additional images have been
> obtained and will be analysed in due course.

> Photometry reported is referenced to an ensemble average of three stars
> (12.8, 13.8 and 15.4 as shown on AAVSO chart).  Precision of photometry 
> for
> single images is 0.006 mag.
