The AASVO's Citizen Sky Project has been producing a series of online talks as a part of a month-long celebration called Astro-April.
In the last couple of weeks we have presented 5 online talks on various astronomical subjects. (If you missed any of them, recordings are posted on the main Astro-April page.) The speakers have been engaging, the questions have been thoughtful, and we've given away $250 in "door" prizes!
The following stars have new or revised sequences since April 9, 2012. If you observe any of these objects please update your observing charts as soon as possible.
Thank you,

April 22, 2012: The blazar OJ 287 (Cancer) has brightened from its low optical state to its high state and is flaring. The Astronomer's Telegram #4057 (S. Zola et al., http://www.astronomerstelegram.org/?read=4057) reports very high optical activity.
Observations of OJ 287 in the AAVSO International Database may be
viewed (http://www.aavso.org/ql),
plotted (http://www.aavso.org/lcg), or
April 21, 2012: The discovery of a possible nova in Sagittarius [V5589 Sgr] was posted on the IAU CBAT Transient Object Confirmation Page (TOCP, http://www.cbat.eps.harvard.edu/unconf/tocp.html).

In late 2011 we issued a survey focused on the demographics and astronomical background of our membership. The results have recently been published here.
We now have a new, follow up survey prepared. This one is focused on the strategic direction of the AAVSO and the operations of the organization. The survey asks questions about the future direction of the organization, staff, officers and council and much more.
The AAVSO is happy to provide a copy of Bob Nelson's O-C files for Eclipsing Binaries for 2012. These files can be used for observation planning, and are a valuable resource for EB observers.
Thanks once again for Bob Nelson for providing this service to the EB community.
The March 2012 Solar Bulletin is now available.
In late 2011 we asked you to fill out a membership demographic survey. Participation in the survey was remarkable, with 615 people responding. An analysis of the results have recently been submitted to the JAAVSO and accepted for publication. A pre-print can be downloaded via the link below.
Also, Kevin Paxson created a Google Map of members and observers, which can be viewed via the link below:
