RX is a red variable, and BL is of the same general type, though its variations are too small to be of interest to amateur observers. It has been plotted just in case you think you may have discovered a "new" red variable star. It also has a normal star designation, that of m2 Cancri. The main star of our chart is not very well observed, so it may be worth taking a fortnightly or monthly look at it.
