This month sees the start of an observing campaign on two bright YSOs - AB and SU Aur. For fuller details, go to this page 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.
