April 9, 2013: In AAVSO Special Notice #346 (http://www.aavso.org/aavso-special-notice-346), IU Leo was said to have a close companion about 2 arcsec to the NE. This is not correct - it is IY UMa that has this close companion.
We extend sincere apologies to Dr. Szkody for misquoting her and to our readers for the error.
This AAVSO Special Notice was compiled by Elizabeth O. Waagen.
