(from vsnet-alert 316, Kevin West )
To VS Net,
I would like to draw your attention to my discovery of a new late type variable in Canes Venaticium.
The star is SAO 44590, HD 116475, BD +47 2053 Further details appear in IBVS 4289 and the Astronomer magazine (UK>. The discovery is particularly important because the star has been used for decades as a comparison for V Canes Venaticium. It appears as star 69 on the BAA chart for Y, TU, and V Canes Venaticium (1984 Apr 12).
