Erupción de la nova recurrente T Pyxidis
14 de abril de 2011

La nova recurrente T Pyxidis ha sido descubierta en erupción. Fue detectada por M. Linnolt (Hawaii, Estados Unidos) con magnitud visual 13.0 en abril 14.2931, 2011 (JD 2455665.7931), y confirmada por A. Plummer (m(vis)=12.2, JD 2455665.8847) y S. Kerr (m(vis)=11.3, JD 2455665.9410).  Esta es la primer erupción de T Pyx desde el 7 de diciembre de 1966, hace casi 45 años. Se solicitan urgentemente observaciones de esta rara variable eruptiva, comenzando inmediatamente.
