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

Special Notice #51: V5558 Sgr chart update

June 29, 2007

The slow nova V5558 Sgr appears to be close to orbrighter than m(vis) = 7.6, and brighter comparisonstars than the initial bright limit of the chartmay be required. If necessary, please use the two additional comparison stars for this object that may be obtained by plotting a 240-arcmin chart with VSP:
