About this image

One of the stars in my programme of SR and L variables is CT UMa, an LB star with a published range of 10.5 to 10.9 p. This star is shown in red in the chart and during 2018 it has been varying between 10.0 and 10.9 V.

While sorting out comparison stars for CT, I noticed that one of my set of stars appeared itself to be variable so I have been monitoring this star (TYC 4384 643) as well and it is shown in blue in the chart. So far, it has varied between 10.3 and 11.2 V.
