AAVSO Special Notice #149: Outburst of the suspected eclipsing polar CSS 081231:071126+440405

Observer Arto Oksanen reports that the deeply-eclipsing polar 
CSS 081231:071126+440405 appears to have re-entered a bright state 
immediately after declining from a previous bright phase last week.
Observations are ongoing, but he reports that the star reached
a peak magnitude of CV=14.8 near the time of eclipse around 
JD 2454917.35 (2009 March 26.85 UT).  

Arto Oksanen has provided a light curve showing the present 
lighcurve versus last night's, clearly showing the brightening over 
the past day:

Observations of this very interesting source are encouraged during
the current bright event through its eventual fade.  Eclipses of this 
star are extremely short, and it is likely that you will not detect the
object in full eclipse.  Please balance integration times between good
signal to noise and good time resolution, at least outside of full
eclipse.  Filtered photometry is only encouraged for larger-aperture
telescopes.


CSS 081231:071126+440405 is located at the following coordinates (J2000):

RA: 07 11 25.99 , Dec: +44 04 05.0
