NOVA SAGITTARII 2006
     C. Jacques and E. Pimentel, Belo Horizonte, Brazil, write
that their unfiltered CCD images taken on Feb. 19.34 UT show the
new object (cf. CBET 405) at mag 8.6 at the following position:
R.A. = 17h58m52s.61, Decl. = -36o47'35".1 (equinox 2000.0).
Jacques adds that a USNO-B1.0 catalogued source that is also
visible on a red 1979 Digitized Sky Survey plate (with limiting
mag 19.9) has red mag 17.4 and position end figures 52s.60, 36".2.
     W. Liller, Vina del Mar, Chile, reports that a low-dispersion
CCD spectrogram of the H-alpha region (resolution 0.32 nm/pixel)
of the apparent nova, taken on Feb. 19.38 UT with a 0.2-m Schmidt
telescope (+ 75 lines/mm grating), shows a moderately strong
H-alpha emission with a FWHM of 630 +/- 25 km/s.  A weak P-Cyg
profile may be present approximately 535 km/s from the peak of the
H-alpha emission.
     Visual magnitude estimate by A. Pearce, Nedlands, W. Australia:
Feb. 19.848 UT, 9.2.
