                        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

    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.

    Notes:
    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 website (www.aavso.org<http://www.aavso.org/>) 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
    observations_at_aavso.org<mailto:observations_at_aavso.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.

    Good observing!

    Elizabeth O. Waagen
    Interim Director
