AAVSO 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

PEP observers should use the 65 sequence star as their comp,
and the 60 sequence star as their check.

Good luck and clear skies!
Arne Henden
