After checking this star in VSX, I found out that its type was changed to "non-variable". It is constant in ASAS-3, Hipparcos and GCPD data. I hope I don't have too many of these stars om my observinglist! :-)
It is nice to see that, except for two outliers (6.1 and 6.5) all my observations of this star are between magnitude 6.2 and 6.4.
Maybe two possible improvements for WebObs:
- a warning if a dated chart is used, this gives me the opportunity to update it.
- a warning if a star is a non-variable
