Special Notice #61: N Vul 07 is now V458 Vul

August 22, 2007: CBET 1038 reports that the GCVS team has given the nova the formal name of V458 Vul. Please use 1950+20 V458 Vul for all future submissions through WebObs.

Special Notice #56: N Vul 07 [V458 Vul]

August 9, 2007: N Vul 07 (CBET 1027, AAVSO Special Notice #55) is most likely a nova [V458 Vul]; high-resolution spectra are being analyzed to confirm the object's nature. An AAVSO Alert Notice will be issued later, but the purpose of this special notice is to inform observers that:

  - N Vul 07 (19:54:24.64 +20:52:51.9 (2000.0)) has been added to the AAVSO files as 1950+20 N VUL 07.

November 20, 2007

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)].

Special Notice #82: Update on possible X-ray transient/Nova [V598 Pup]

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
