Is MP Geminorum an Eclipsing Binary With a Very Long Period?
Received September 7, 2011; revised January 26, 2012; accepted January 27, 2012
Perhaps MP Gem is a very long-period eclipsing binary star. Only nine observations of a minimum exist to this day. The author observed the star on plates of the Sonneberg Observatory and did not find any further minima. Continued monitoring by CCD observers is recommended.
