AAVSO ALERT NOTICE 307 (July 6, 2004)
SUBJECT: 1706-30 Nova Scorpii 2004
Object: 1706-30 N Sco 04 (ASAS 171251-3056.6)
Event: Nova in Scorpius
Discovered By: Grzegorz Pojmanski, Warsaw University Astronomical Observatory, Poland, in ASAS-3 (All-Sky Automated Survey) data (IAU Circular 8369)
Discovery Magnitude: 11.983 V
Discovery Date: July 3.14635 UT (reported by Pojmanski July 5)
Position: (2000.0) measured by H. Yamaoka, Kyushu University, Japan, on image taken by G. Bolt, Craigie, Australia (IAU Circular 8369):
R.A. (2000): 17h 12m 51.281s
Decl. (2000): -30o 56' 37.57"
Spectra: A spectrum taken by M. Fujii, Bisei, Okayama, Japan, Jul 6.51 UT and reported by D. Nogami, Hida Observatory, Kyoto University, Japan (IAU Circular 8369) indicates the object to be a nova. According to Nogami, the spectrum resembles that of the slow nova V723 Cas (N Cas 1995) (see AAVSO Alert Notices 213, 214, 217, 218, 219, and 230, and V723 Cas light curve on the AAVSO website at http://www.aavso.org/data/lcg/  ).
AAVSO Chart(s): 'd' scale chart is being prepared and will be posted at http://www.aavso.org/cgi-bin/searchcharts3.pl?name=n%20sco%2004 
Report Object to the AAVSO as: 1706-30 N SCO 04
Observations Reported to the AAVSO: Jun 27.2190 UT, <14.0: V, G. Pojmanski, Warsaw University Astronomical Observatory, Poland, ASAS-3 data (via IAU Circular 8369); Jul 4.9847, <11.9, Tech-pan film with orange filter, W. Liller, Vina del Mar, Chile; 5.2390, 11.294 V, Pojmanski, ASAS-3 data (via IAU Circular 8369); 6.0521, 11.0 R, P. Cacella, Brasilia, Brazil (via IAU Circular 8369); 6.2806, 11.1, M. Linnolt, Honolulu, HI; 6.4132, 10.8, J. Bedient, Honolulu, HI.
a. No x-ray source was found within 30" of the object's position, according to D. Nogami, suggesting the object is not a dwarf nova (IAU Circular 8369).
b. If this is a slow nova, it may take several weeks to brighten to maximum, with fluctuations in brightness along the way. Visual and CCD observers (and PEP observers if it brightens into range), please observe it every clear night, being careful not to let your earlier observations influence you, and report your observations to AAVSO Headquarters. Please make sure to indicate which comparison stars you used.
c. An AAVSO web page  will be created tomorrow for N Sco 04. We invite you to submit photos, spectra, etc. of this object to be placed there.
d. For more information on N Sco 04, please see IAU Circular 8369 (ed. Daniel W. E. Green).
SUBMIT OBSERVATIONS TO THE AAVSO
We encourage observers to submit observations via our web site (online data submission tool WebObs), or by email in AAVSO format to firstname.lastname@example.org. If you do not have AAVSO Observer Initials, please contact Headquarters so we may assign them to you. The answering machine at AAVSO Headquarters is on nights and weekends; use our charge-free number (888-802-STAR = 888-802-7827) to report your observations, or report them via fax (617-354-0665).
Many thanks for your valuable astronomical contributions and your efforts.
