AAVSO Alert Notice

AAVSO Alert Notice

Alert Notices are published irregularly and alert those interested to the discovery of novae, unusual activity of variable stars, and requests from astronomers for simultaneous AAVSO observations. They are available online or by e-mail.

Special Notice #104: Photometric Sequence for V2491 Cyg now Available [Nova Cyg 2008 No. 2]

April 17, 2008

Special Notice #418: RX And monitoring needed for VLA observations

July 5, 2016: Further to AAVSO Alert Notice 539, Deanne Coppejans and colleagues request optical monitoring of the Z Cam dwarf nova RX And in support of their campaign to observe it with the Very Large Array (VLA) in their ongoing radio jet research.

Deanne writes in a post to the AAVSO Forum thread on this campaign: "We are going to try and catch RX And in quiescence again in the next three weeks. The optical coverage of it is still sparse, so any observations you take of it will be extremely useful."

Special Notice #41: Chart Available for N Oph 07 [V2615 Oph]

March 23, 2007

You can now retrieve a chart and sequence for the apparent nova in Ophiuchus [V2615 Oph] from:

obsolete link: [http://www.aavso.org/observing/charts/vsp/]

2016 link: https://www.aavso.org/vsp

enter N Oph 07 for the object name. When conditions permit, we will obtain an all-sky calibration for this field from Sonoita Research Observatory.

Special Notice #406: KIC 02856960 entering eclipse window

August 7, 2015:  Further to AAVSO Alert Notice 525, we are entering the critical period of observations for KIC 02856960.  Time series observations are urgently requested for this eclipsing binary beginning immediately (2015 August 07, JD 2457242) and continuing for the next five days, through the end of 2015 August 12.

Special Notice #405: Request for Monitoring of V4641 Sgr

August 4, 2015:  Dr. Gregory Sivakoff (U. of Alberta) has requested optical monitoring of the galactic microquasar V4641 Sgr beginning immediately, and continuing for the next 120 days, or until it is no longer observable from your location.

Special Notice #398: Bright Transient in Sgr (PNV J18142514-2554343) [V5667 Sgr]

February 13, 20115:  Patrick Schmeer (SPK, Bischmisheim, Germany) reports the announcement on the CBAT Transient Object Confirmation Page (TOCP) of the discovery of a bright transient in Sgr [V5667 Sgr] on 2015 February 12.852 at an unfiltered magnitude of 10.9 by K. Nishiyama, using a 105-mm f/4 camera lens with an SBIG STL6303E CCD camera.  Nishiyama notes nothing is present on a previous image from 2015 February 02.887.  The transient has been independently confirmed with two pre-discovery images: by H.
