recurrent nova

Special Notice #270: Possible Recurrent Nova in the LMC = TCP J04550000-7027150 [Nova LMC 2012]

March 27, 2012:  A possible nova in the LMC [Nova LMC 2012] discovered at unfiltered magnitude 10.7 on 2012 March 26.397 UT (name of discoverer not given) was reported on the IAU CBAT Transient Objects Confirmation Page (TOCP). Spectra indicate the object may be a recurrent nova.

J. Hambsch reports that as of March 28.04 UT, the object appears to be fading fast and is at least one magnitude fainter than 24 hours ago.

Alert Notice 451: Monitoring of the Symbiotic Variable RT Cru Requested

January 27, 2012: The symbiotic variable RT Cru has brightened in hard x-rays. Dr. Jeno Sokoloski, Columbia University, has requested AAVSO assistance in monitoring RT Cru both now and in the future to see if it is doing anything unusual in the optical. The Swift/BAT hard X-ray light curve shows RT Cru has apparently been gradually brightening over the past few years.  

Special Notice #244: Continued close monitoring of T Pyx requested

Continued close monitoring of T Pyx requested

June 30, 2011: Since its outburst on 2011 April 14 (see AAVSO Alert Notice 436), the recurrent nova T Pyx has been very well monitored by visual and instrumental observers who can reach -32o. Thank you! Currently T Pyx is visual/V magnitude ~8.3.

Campaign to monitor the recurrent nova T Pyx throughout 2011 eruption

April 15, 2011: Dr Bradley Schaefer (Louisiana State University) has initiated an international campaign to observe the recurrent nova T Pyx during its current eruption (see AAVSO Alert Notices 436 and 437). He asks the assistance of the AAVSO and our observers, and writes:

Campaign to monitor the recurrent nova T Pyx throughout 2011 eruption

April 15, 2011:  Further to AAVSO Alert Notice 436, a fast photometry observing campaign has been initiated by Dr. Bradley Schaefer (Louisiana State University) to monitor the recurrent nova T Pyxidis throughout its current eruption.

Special Notice #231: T Pyx Observations Requested

February 1, 2011: Sumner Starrfield (Arizona State University) has informed us that Chandra is currently observing the cataclysmic variable T Pyx.  He and his colleagues would like supporting optical monitoring of the star during the visitation.  One visit is happening now; the next and final visit will occur on February 5 (UT).

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.
