Aim to monitor 2-3 open clusters each year for 2-3 weeks each, during spring and summer. During a given run, we monitor a single cluster for around 20 nights and do not spend time on additional targets. I filter only, plus color information on photometric nights to create CMDs and estimate contamination. Choice of cluster mainly depends on richness, observability, distance, galactic coordinates (contamination) and foreground reddening. Feb run produced ~3000 stars monitored to <1% photometric precision. May-Jun run produced ~5000 stars monitored to <1% photometric precision. Both numbers correspond to around 10-15% of the total number of objects we monitor in each of the respective fields. Preliminary photometry/candidate identification done during run. Will do spectral typing to help identify blends during Jul and Sep Magellan runs. Nights of data hoped for in 2003: ~55 obtained, no more expected this year.
