                  ***** NOVA SAGITTARII 1999 *****

This nova was discovered by Minoru Yamamoto, Okazaki, Aichi, Japan on two photos from Apr. 25.731 UT. According to Y. and R. Kushida the object is located at R.A. = 18h07m36s.22, Decl. = -27o20'13".5 (2000.0). A low-resolution CCD spectrogram by W. Liller showed that the object was a nova. Observations from Apr. 27 indicate a magnitude of 7-8, while it was at mag. 8.6 at discovery and invisible and fainter than 11.5 on Apr. 21. [ref. IAUC 7153, IAUC 7154, vsnet-obs 20276, vsnet-obs 20278].

I have prepared a chart of Nova Sagittarii 1999, which is based on the Tycho catalogue and available via the Internet address http://www.astro.uio.no/~bgranslo/varchart.html.

                                  Yours Sincerely,
                                  Bjorn H. Granslo
