COMPARISON STARS FOR NOVA AQULIAE 1993
These are measured off sets from a new chart by Mati Morel (New Castle NSW
Australia).
The chart uses an accurate position from R H McNaught (IAUC 5798)
and has a scale of 20"/mm and 5"/mm.
S. Kiyota (Japan) has obtained V CCD magnitudes for some comparison stars of
which some are the same as Morel's chart.
----------------------------------------------------------------------------
Following V-band CCD photometry of the comparison stars have been
reported from S. Kiyota (Ibaraki, Japan). His system closely
approximates the standard Johnson V.

S. Kiyota reports following CCD V magnitudes of stars around Nova Aql.
(I am now asking for positional identifications for each stars.)
