Charts and Sequences Update January 2012

There are over 100 new and revised charts and sequences since the last update in November. Many of these are for stars in the newly formed YSO Section Program, southern stars with new photometry from APASS and campaign targets. The rest are revisions based on issues reported to CHET and requests for new sequences from our observers.

New VSP upgrades

We held another VSP workday this week and tackled a few VSP bugs and feature requests. Most of the changes are minor and I'll list them below. We did not get to everything on the list. Our next workday will probably be in a couple of months. Feel free to submit feature requests or bug reports to aavso at

As always, thanks to Michael Koppelman and Chris Watson for taking time out of their day to help us!
