We are conducting a survey to learn more about the demographics of our members, observers and anyone affiliated with or interested in the AAVSO. Information may be used for purposes such as making strategic plans for the AAVSO, writing grant applications, planning observing campaigns, writing papers about our membership, etc.
Identifiable survey data will never be shared with anyone outside of the AAVSO.
Longtime friend of the AAVSO, Dr. Chris Mauche (Lawrence Livermore National Lab), has published a paper about AE Aqr in which he uses data from AAVSO observations. It was submitted for inclusion in the proceedings of the conference "The Golden Age of CVs and Related Objects".
The ArXiv link to the black/white paper is here.

ej152: Periodicity Analysis of the Semiregular Variable Star
EV Aquarii
November 2, 2011: The observing campaign described in AAVSO Alert Notice 443 (M. Templeton) has been extended through the end of November 2011. One of the original targets, NGC 6814, has been removed from the target list for the remainder of the campaign.
The paper "Modern observations of Hubble's first-discovered Cepheid in M31" has been accepted for publication to PASP, and is now available on arXiv.org.
AAVSO Newsletter 50, October 2011, is now online.
October 25, 2011: Dr. Paula Szkody (University of Washington) has requested the help of AAVSO observers in monitoring the WZ Sge-type cataclysmic variable SDSS J080434.20+510349.2 (SDSS0804+51) in support of Hubble Space Telescope ultraviolet spectroscopic observations scheduled for 20:52:40 - 23:32:35 2011 November 3 UT (the night of Wednesday, November 2/3) (JD 2455869.36991-.48096). Nightly observations are requested beginning immediately and continuing through November 30.

Event: Outburst of the UGWZ Candidate BW Scl
October 21, 2011: The short period cataclysmic variable BW Scl appears to be in outburst. The object was detected in outburst at m(vis)=9.6 by M. Linnolt on 2011 October 21.3146 (JD 2455855.8146), and confirmed by A. Plummer at m(vis)=9.4 on October 21.3424. Observations of this object are encouraged. The object has conflicting classifications in astronomical literature, but is probably a WZ Sge-type dwarf nova rather than a novalike variable.
BW Scl is located at the following (J2000) coordinates:
