Alert Notice 393: Monitoring for a planetary transit of HD 80606

February 3, 2009: Dr. Greg Laughlin (Lick Observatory) requests intensive time-series photometry of the possible transiting extrasolar planetary system HD 80606. This system, recently in the news due to the extreme temperatures to be found on the planet, is predicted to reach conjunction on or around HJD 2454876.5 (2009 Feb 14.0 UT), and there is a low but significant probability (<15%) that the system is eclipsing. If it eclipses, the duration of the eclipse may be as long as 17 hours.
