R Leonis Minoris

The membership database is currently undergoing upgrading/testing. Web functions that involve an interface with the member database (webobs, etc.) may experience intermittent problems. We hope to have this issue resolved within 24 hours (by 5pm Eastern Time on October 1st or 12:00 UT). Thank you for your patience.

R LMi is a fine northern Mira variable with a substantial range, and a period just over one year (372 days).  R LMi shows cycle-to-cycle variations like many Mira variables do, and so it never quite puts on the same show from year to year.  The star is a known maser source, and it's also been studied with interferometry and found to be asymmetric -- if you were to have a "close up" view of the star, its face would have significant variations across it.
