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:
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:
