  I saw a note on the Nova Network that Yukio Sakurai of Japan
has reported a possible nova in Sagittarius:  His report
states

    1994 May 20.710 U.T.        mpv= 10.8
          R. A.  18h 27m 28s
          Decl.  -17 14 14     (1950.0)

  I got UBVRI CCD images of the field last night, May 23 UT, but
I don't have access to the Palomar Sky Survey at the moment,
so I can't tell if what I see is a new star, or just an old one.
Can someone help me out?

  Here's a very rough ASCII version of an I-band image:
the central object 'x' is the brightest object in the field, which is 
5.8 by 5.8 arcmin and probably shows stars around mag 9-13.
                           E

  Here 'o' marks a relatively bright star, '.' a faint star, and '#'
a close triple star.  Again, 'x', the possible nova(?), is the
brightest object in the field, by about one magnitude.

  I've placed a copy of the I-band image into our anon FTP area:
connect to astro.princeton.edu and go to the "richmond" directory --
there is a FITS file called "scox1.fts".

  If anyone wants to acquire more photometry of this object (if
it turns out to be real) and is willing to do all the reductions,
please contact me.  I certainly don't have time to do it :-(
