I wa setting up my June observing list and selected BS Vul. There is a possible problem. VSX and the ephemeris (pdf mislabled as RR Lyrae) list the V mags as 10.9 - 11.6 V. But the data history show variation up to 9.7V. Do we have a probelm, or is BS Vul really brighter than the ephemeris and VSX show?

Hi Ed,
You were right, for some reason the magnitudes inherited from the GCVS (based on a 1938 paper in PZ) were a whole magnitude fainter than V.
I corrected the range and took the chance to improve the ephemeris a bit.
Thanks,
Sebastian
Thanks Sebastian, that clears it up.
