[vsnet-sequence 239] BV sequence for VY Tau



     Remington Stone published a UBV sequence for the T Tauri-type star
VY Tau on IBVS 2380.  The on-line AAVSO chart shows no photoelectric/CCD
data, so this sequence should be useful for revising the chart, as well as
providing calibration for wide-field images in the area.
     The stars were identified only on a chart in Stone's paper, so the list
below shows coordinates (from GSC-ACT) and identifications along with the
BV data.  In addition, I have adopted photometry from Herbig for two brighter
stars, and added spectral types from Metreveli or the HDE.  All the stars
down to B mag ~12.5 have spectral types.
