Liller's nova suspect

I have received the following nova suspect report from W. Liller. A quick look of catalogs around the reported position has yielded no variable star candidates (within several arcmin) nor 12-micron bright IRAS source. Confirmatory observation is most urgently requested.

Dear Dr. Kato -

Last night I photographed a nova suspect as follows:


Mag 7.7 at R.A. 14h 23.6m,  Dec -69d 09'.  Photo taken Aug 23.0125, 1999

Previous photo: July 15.993, fainter than mag 11.

The star about 7 minutes of arc to the northwest has a V mag of 7.35, acc.
to Project Pluto's Guide 7.0.

My photos are taken with Kodak Tech Pan and an orange filter so the
magnitude I give is only roughly V.

The sky looks doubtful for tonight over here, but I'll try for a CCD frame
(to get a more accurate position) and a spectrum (CCD with a 4-inch
diameter prism over the objective).

If someone would confirm it, it would make me very happy!

                                With best personal regards,  William Liller

I managed to observe Nova Circini 1999 through my 16" reflector.  I then
examined the Second Generation DSS image downloaded and together with Bill
Lillers more precise position, I could not identify any progenitor star on the
DSS image.

Andrew
