Charts and Sequences Update November 2011

 Dear AAVSO Observers,

The following charts and sequences have been revised since the last update September 29, 2011. This batch of updates includes many stars from the YSO Section Observing Program, as well as stars visible only from the southern hemisphere.

There are also several updated sequences for HMXBs and WR stars from Gordon Sarty's HMXB Campaign.

A large percentage of these are answers to reports made to the CHET, the chart error tracking tool.

http://www.aavso.org/CHET

Others are requests for new sequences for stars that previously had no AAVSO selected comparison stars. Requests for new sequences should be made using the suggestions on this page:

http://www.aavso.org/request-comparison-stars-variable-star-charts

One notable update is that for the prototypical star, T Tauri, for which observers have long endured a poor sequence.

If you observe T Tau, or any of the other stars on this list please update your charts immediately.

If you have been looking for some interesting stars to enliven your own observing program, try some of these Young Stellar Objects, many of which reside in beautiful or interesting, nebulous star fields.
