Since I'm a photometrist, I tend to think in V mags and colors,
rather than separate magnitudes, so: B-V = +0.12 and U-B = -0.88.
The usual colors of the star are B-V = -0.11 and U-B = -0.90, and
V = 2.32. So evidently the star is still brighter than normal,
and the U-B color seems the same, but B-V is much redder. Is that
possible?
