Bidding in a silent auction is done privately via pre-printed sheets of paper set up at the auction table. You may bid on multiple items at once. Afterward, the written bids are examined and the person who bid the highest for each item claims and pays for that item.
Please keep in mind that this is a fundraising event. Items are usually purchased for prices exceeding the item’s retail value. Please be generous. All the proceeds go directly to the general fund and support critical AAVSO operations.
October 11, 2016: Further to AAVSO Alert Notice 549, observations of the dwarf nova RX And are urgently requested immediately. The system *may* be going into outburst, and confirmation is essential in order to know whether to trigger ToO observations with Chandra and other instrumentation.
October 4, 2016: Dr. Ashley Pagnotta (Louisiana State University) has requested AAVSO assistance in monitoring the recurrent nova V2487 Oph in order to catch and observe its next outburst.
October 4, 2016: In AAVSO Alert Notice 554 the star was inadvertently referred to as V420 Oph in the sections creating charts and reporting observations.
Note added October 4, 2016: In the original version of this Alert Notice, V420 Aur was referred to as V420 Oph in the sections on creating charts and reporting observations. Also, the range was given as V=7.15-7.35 when the correct value is V=7.35-7.51. The text below has been corrected. Apologies to the PI's for the error.
AAVSO Newsletter 70, October 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.
September 30, 2016: Further to AAVSO Alert Notice 551, Dr. Mark Reynolds (University of Michigan) informs us that the cataclysmic variable GDS_J1701281-430612 will be observed by the HST/COS on
Discovered by: All Sky Automated Survey for SuperNovae (ASAS-SN) (K. Stanek (Ohio State University) et al., ATel #9538; reported to CBAT via J. Strader (Michigan State University))
Discovery magnitude: 9.11 V +/- 0.01, using ASAS-SN robotic 14-cm telescopes
September 22, 2016: SN 2016gkg (announced as AT2016gkg) was discovered by Victor Buso (Rosario, Argentina) on 2016 September 20.2484 UT at CCD magnitude (clear filter) 17.6 +/-0.5, rising to 14.5 +/-0.2 on Sep. 21.1398. His discovery was reported to the Transient Name Server by Sebastian Otero (Buenos Aires, Argentina). It was confirmed by ASAS-SN on Sep. 21.29 UT (B. Nicholls (Mt.
September 20, 2016 : Dr. Kirill Sokolovsky (National Observatory of Athens and Sternberg Astronomical Institute, Moscow State University), has requested AAVSO assistance in monitoring the ongoing microlensing event Gaia16aye beginning immediately to catch transient behavior occurring now and continuing through the end of October (or until further notice).
