[Aavso-photometry] GJ436b comp stars...constant over time?

[Tom Krajci]

A bunch of folks have been working on GJ436b for some time.  Two comp 
stars are most often used:  HIP 57103 (3 - 4 arcminutes NE) and GSC 
1984-1884 (3 - 4 arcmin N).

Have these comps shown any variability over time?

Thanks in advance.
