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:

Alert Notice 434: Outburst of NSV 1436

March 30, 2011: The cataclysmic variable NSV 1436 has been discovered in outburst.  This is the first bright outburst of this star observed since 1948, and followup observations are strongly encouraged.  Little is known about the nature of NSV 1436, and observations may help shed light on whether the star is an infrequently outbursting normal dwarf nova, a WZ Sge star, or recurrent nova.

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.
