Note: This campaign is the subject of the AAVSO Spectroscopy discussion forum thread: https://www.aavso.org/p-cyg-monitoring-intrinsic-h%CE%B1-flux
Also, spectroscopy reports should be submitted to the AAVSO Spectroscopy Database (AVSpec, https://www.aavso.org/apps/avspec/). - Elizabeth O. Waagen, 20 May 2020
CONTINUED THROUGH 2022 AT LEAST
A partir del viernes 13 de mayo, la AAVSO tendrá una sección en el programa Espacio Profundo Radio, que se emite todos los viernes entre las 20 y 21 GMT. El programa es conducido por Cristina Ruffa y auspiciado por Espacio Profundo, una de los sitios web más conocidos en el ámbito latinoamericano.

The following is a chat transcript from May 9, 2011. The topic of the chat was the History of the AAVSO and variable star observing with guests Dr. Mike Saladyga and Dr. Tom Williams. Some footnotes are at the bottom.
<DocKQR> Hello Folks!
The American Association of Variable Star Observers (AAVSO) is looking
for an administrative assistant with immediate availability. The ideal
candidate will work well in a team environment, but demonstrate
initiative and perseverance. The AAVSO is a small non-profit in the
Fresh Pond area of Cambridge, serving a membership of amateur
astronomers across the world who wish to contribute scientific
observations of stars that vary in brightness. We are celebrating our
Mira variables are the longest-observed class of stars for which we have long-term quantitative data that allow us to study their behavior over centuries-long periods of time. Fortunately for us, they're also easy to observe and monitor, having some of the largest amplitudes of all variables, and hundreds of them are bright enough that they're within reach of astronomers with modest telescopes.
Its an old story that astronomy is being drowned in data and its only getting worse. We have needed a "central clearing house" of sorts and the Virtual Observatory aims to be one solution in this vein.
Astronomers have also experimented with various methods of alerting interested people as to events as they happen and when they need to be followed up on. This is the concept behind VOEvents.
April 28, 2011: In AAVSO Alert Notice 438 on Supernova 2011by in NGC 3972 (issued 2011 April 28), the position was attributed to the wrong object. Here is the corrected text:
Position: R.A. = 11:55:45.56 Decl. = +55:19:33.8 (equinox 2000.0)
SN 2011by is about 5.3" east and 19.1" north of the center of NGC 3972.
Sincere apologies for the error.
This Alert Notice was issued by Elizabeth O. Waagen.

The Manual for Visual Observing of Variable Stars has been updated to reflect changes to the VSP and WebObs that happened when the new website was launched last summer. This mostly affects Chapters 2 and 7. To download these and other chapters, or the entire Manual, please click on the link below:
http://www.aavso.org/visual-observing-manual
You will also find versions of the Manual translated into seven other languages on this page.
Stay tuned for the Portuguese verson, due to be completed soon!
