AAVSO Abstracts 1951 - 1971

This is part of our ongoing series to highlight new features of the new AAVSO web site.

Matt Templeton scanned all of the abstracts and put them online in PDF format. The abstracts cover items presented at meetings, but often include much more info than a modern day abstract. For example, the last issue includes abstracts that are over 3 pages long, meeting memories, history of the AAVSO articles and even a poem! Here is his description of the abstracts from the first paragraph on the web page:

AAVSO 2011 Calendar Survey

The AAVSO is making another calendar! The calendar for 2011, our Centennial year, and will include lots of AAVSO historical notes - important dates, pictures of how variable star observing has evolved in the last 100 years, notes about the legacy of our Directors. We're still planning the last details, but we expect the cost to be between $10 and $15 each (including shipping). We're planning on having the calendars finished and ready to ship out during November.  This is one memento from the AAVSO that you don't want to miss!

Alert Notice 426: Rescheduled request for observations of V455 AND in support of HST observations

October 5, 2010: As originally announced in AAVSO Alert Notice 423, Dr. Paula Szkody (U. Washington) has requested the help of AAVSO observers in monitoring the WZ Sge-type cataclysmic variable V455 And in support of Hubble Space Telescope ultraviolet spectroscopic observations.

Alert Notice 425: Monitoring of HBC 722 and VSX J205126.1+440523 Requested

October 1, 2010: Dr. Colin Aspin (U. Hawai'i) has requested the help of AAVSO observers in performing long-term photometric monitoring of the two new young stellar objects (YSOs) in Cygnus, HBC 722 and VSX J205126.1+440523 (see AAVSO Special Notice #216).

Special Notice #218: Outburst of the UGWZ star SDSS J080434.20+510349.2

September 21, 2010: As announced by Hiroyuki Maehara in vsnet-outburst 11547, the WZ Sge-type dwarf nova SDSS J080434.20+510349.2 is in outburst, and is also showing evidence of superhumps (vsnet-outburst 11551).  Both visual and CCD observations -- including CCD time-series observations -- of this outburst are encouraged.  The most recently posted visual observation by Patrick Schmeer (vsnet-outburst 11556) indicates the star is currently around m(vis) = 12.7.

Alert Notice 424: Monitoring and Study of V2672 Oph

September 14, 2010: V2672 Oph (Nova Oph 2009) was discovered by Koichi Itagaki in outburst on August 16, 2009 (see AAVSO Alert Notice 402 and IAUC 9064).  It peaked at about magnitude 12, and rapidly faded.  Low- and medium-resolution spectroscopy showed broad, prominent H_alpha emission with FWHM 11500 km/s on top of a featureless, but very red, continuum.
