The following variable stars have either new or revised sequences and charts. If you observe any of these stars you should update your charts to the most recent version. 

Thank you, 
The AAVSO Charts and Sequences Team 

There is now a sequence available for SN2011B. 

You will need to specify the coordinates (I used 08 55 48.50 +78 13 02.7 from the discovery telegram) to plot a chart, or you can simply download this E scale DSS image chart and print it.

Enjoy!
