V5558 Sgr chart update
June 29, 2007

The slow nova V5558 Sgr appears to be close to or
brighter than m(vis) = 7.6, and brighter comparison
stars than the initial bright limit of the chart
may 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:

The brighter of the two new comparison stars
(HD 167771) extends the sequence for V5558 Sgr 
to m(vis)=6.5.  As before, both visual and 
instrumental photometric observations are 
urgently requested as this object continues 
to exhibit anomalous behavior.

Coordinates for V5558 Sgr are: 
RA 18:10:18.26, Dec -18:46:51.9 (J2000)

Please report observations to the AAVSO as 
1804-18 V5558 SGR.
