Eruption of nova T Pyxitis
(2011)

 

Eruption discovered by M. Linnolt (Hawaii, United States) at a visual magnitude of 13.0 on 2011 April 14.3. This is the first outburst of T Pyx since December 7, 1966, nearly 45 years ago.

Position (2000.0) = RA : 9h04m41.5s - Dec : -32°22'47.5"

April 15.809, 2011 observation (start of exposure)

Setup: Celestron 11 telescope (0.28-m diameter) + LISA spectrograph (sampling = 2.1 A/pixel - R = 1100 - 23 microns slit) + QSI583 CCD camera (5.4 microns pixel - bin. 1x1).
Observatory: Castanet Tolosan (France)
Observer: Christian Buil
Note: Atmospsheric extrinction is corrected. The object is observed only 14° above the local horizon. Atmospheric extinction and instrumental response are evaluated from observation of star HD92845.

V mag. = nearly 8.3
Exposure: 8 x 300 sec.
