New campaign

This month sees the start of an observing campaign on two bright YSOs - AB and SU Aur. For fuller details, go to this page [1] on the AAVSO website. Observers using small instruments should be careful to ensure that, since SU is quite close to AB, the two are clearly separated. For visual observers, a (c) scale chart includes both stars nicely. CCD observers, follow the guidelines mentioned in the article.
