Special Notice #271: Correction to AAVSO Special Notice #270

March 27, 2012:  In the email version of AAVSO Special Notice #270 (Possible Recurrent Nova in the LMC = TCP J04550000-7027150), the discovery magnitude was given as U=10.7. It should have been given as unfiltered magnitude 10.7.

We extend our apologies for the error.

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:

AAVSO Alert Notice 437

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.
