scales of the 2003+17 WZ Sge charts is in fact brighter than magnitude 115.
This star has been marked as "115 VAR?" on these charts.
- The charts for 1818-30B V4739 Sgr have been revised. The 'b' scale has
been updated with more magnitudes and the 'd' scale has been edited to remove two bright "stars" to the

companion star and a 'g' scale chart is now available for the WZ Sge field. (PEP and CCD observers should also
see our page on Precision Photometry for Comparison Stars in the
Field of WZ Sge.) For more information about the latest outburst of WZ Sge, be sure to see our WZ Sge Outburst Update page.

Her chart have been fixed. The RR Lyr type variable shown on the chart is in fact V362 Her and not V632 Her
as previsously stated.
- The "spurious star" between FZ Cyg and the 100 comparison star on the 1947+38
FZ Cyg charts has been removed. The star in question turned out to be an artifact of the photographic plate
used to make the chart. More information about this topic can be found in the AAVSO Discussion Group
archives.
- We have been notified that the 134 comparison star on the 2047+35 V1329
Cyg 'f' scale chart may be a variable. This star has been dropped from the existing AAVSO
sequence.
- The 'd' scale chart for 1918+04 V1494 Aql (N Aql 99#2) has been edited
to remove a nearby (red) 130 comparison star. New 'f' and 'g' scale
charts have been made for observers wishing to observe this nova as it continues to fade.
We have also added more reversed charts to the chart archives - (8/8/01):

your observations of this object to the AAVSO as 1750-32 V1178 Sco. - (6/29/01)

- The 'd' and 'e' scale charts for 1037+58 IY UMa have been slightly
revised. A nearby galaxy plotted as a star was causing identification problems among many observers. The object
was removed from the 'd' scale (since it is too faint for the scale) and identified as a galaxy on the 'e'
scale.
