February 4, 2016: A multiwavelength (radio and optical) observing campaign on SS Cyg is underway, and AAVSO participation is urgently requested. An AAVSO Alert Notice will be issued February 5 with full details.
The purpose of this Special Notice is to alert observers right now to the need to monitor SS Cyg very closely and report your observations to the AAVSO via WebObs at once. It is likely to go into outburst very soon, and immediate reporting of outburst behavior is crucial to the success of the campaign.
AAVSO Newsletter 67, January 2016 is now available to members
The AAVSO Newsletter is a periodic, general forum that supports our various observing programs with lists of new targets, observing programming ideas, and general information that spans a wide area of interest. Guest writers contribute pieces that can range from current events to book reviews.
Ongoing visual, photometric, and spectroscopic observations of R Aqr about once every 10 days are requested, both to detect and observe the next eclipse and to continue the light curve of this star that has been in the AAVSO observing program for over a century. Elizabeth O. Waagen, August 2017
Thanks to another great volunteer effort by Stelios Kleidis, we now have available a full Greek translation of the AAVSO Guide to CCD Photometry! If you know of anyone who would benefit from this translation, please feel free to spread the word and share the link.
If you would like to volunteer your time to translate this Guide into your native language, please contact Sara Beck (sara (at) aavso.org).
December 15, 2015: Further to AAVSO Alert Notice 503 and AAVSO Special Notice #409, Dr. Margarita Karovska (Harvard-Smithsonian Center for Astrophysics) urgently requests that multicolor and visual AAVSO observations of the symbiotic variable RT Cru continue.
