R Canum Venaticorum is a Mira variable star in the constellation Canes Venatici . It ranges between magnitudes 6.5 and 12.9 over a period of approximately 329 days.[ 3] naked eye , but when it is near its maximum brightness, it can be seen with binoculars.
Thomas E. Espin discovered this variable star , in 1888.[ 8] variable star designation , R Canum Venaticorum, in Annie Jump Cannon's 1907 work, Second Catalogue of Variable Stars .[ 9]
