Dear colleagues,

Optically violently variable quasar QSO B0133+47 = MisV1436 is now
fainter than 18 mag, faintest during last 15 years.

Here is the latest light curve:

This quasar was brightest as 14.0 mag on 2007 Nov. 11 at the discovery
by the MISAO Project. But after that, it seems fading gradually with
variation.

Adolfo San Segundo reported that it is fainter than 18 mag now, and
fading furthermore.

  2010 Aug. 28.056  18.44CR
  2010 Aug. 21.103  18.12CR

This quasar has faded down to 19 mag in the past DSS plates. Maybe it
will become faintest in the history soon.

Best regards,
