Special Notice #55: Possible Nova in Vul [Nova Vul 2007, V458 Vul]

August 8, 2007

CBET 1027 reports that Hiroshi Abe has discovered a new bright nova [Nova Vul 2007, V458 Vul] around August 8, at coordinates

19:54:24.64 +20:52:51.9 J2000

and with brightness V=9.4mag. A possible progenitor star is visible on the POSS-I survey plates at about V=18.

This sounds like an ideal target for northern observers. You can plot the field using VSP:

Special Notice #53: Update on V5558 Sgr

July 9, 2007

V5558 Sgr continues to brighten; recent reports from Neil Butterworth place this nova at V=6.5 or so. We recommend continued monitoring of this slow nova.

At V=6.5, this is an easy target for all observers, whether visual, PEP or CCD. The brightest comparison star on the current VSP chart is V=6.0, so given below is another, brighter, comparison star that we will add to the sequence in the next day or so:

HD 167264 RA=18:15:12.905 DEC=-20:43:41.76
label = 54 V=5.352 (B-V) = 0.050 (U-B) = -0.859
