Patrick has properly pointed out that I was using the finding chart from DS93 instead of DWS97. I was in a hurry to get to a meeting and didn't pay attention to his email. Looking at the *correct* star, about 7arcsec north of the DS93 star, I get the following magnitudes and colors: yymmdd HJD V B-V verr bverr 991013 51464.7870 18.743 0.296 0.024 0.031 991105 51487.7467 18.872 0.256 0.021 0.032 which is a properly blue star. Sorry for the error! Arne
