1. X-ray Transient/Nova = V598 Pup
Further to AAVSO Special Notices #81 and #82, Nikolai Samus, Institute of Astronomy, Russian Academy of Sciences, announced (IAU Circular No. 8898, D. W. E. Green, ed.) that the bright x-ray transient and apparent nova has been assigned the name V598 Puppis [07:05:42.7 -38:14:42 (equinox 2000.0)].
November 19, 2007: Further to AAVSO Special Notice #81, precise coordinates for the optical counterpart of the new X-ray source XMMSL1 J070542.7-381442 [V598 Pup] (Read et al., ATEL 1282) have been determined. The (J2000) coordinates are
RA 07:05:42.51 (+/- 0.05 arcsec) , Dec -38:14:39.3 (+/- 0.08 arcsec)
Coordinates were determined by A. Henden using V-band images supplied by S. Dvorak.
This object has now been entered into the AAVSO Variable Star Index (VSX) as: VSX J070542.5-381439
November 18, 2007: Read et al. (ATEL #1282) report the discovery by XMM-Newton of a very bright new transient, XMMSL1 J070542.7-381442 [Nova Pup 2007 = V598 Pup], located at
07:05:42.7 -38:14:42 J2000
