V5115 SAGITTARII = NOVA SAGITTARII 2005
     N. N. Samus and E. Kazarovets, Institute of Astronomy, Russian
Academy of Sciences, inform us that the designation V5115 Sgr has
been given to this nova (cf. IAUC 8500, 8501).
     Visual magnitude estimates:  Mar. 30.127 UT, 7.7 (K. Hornoch,
Lelekovice, Czech Republic); 30.20, 8.0 (A. Pereira, Cabo da Roca,
Portugal); 30.273, 7.7 (R. Y. Shida, Sao Paulo, Brazil).


SUPERNOVA 2005ay IN NGC 3938
     S. Taubenberger, Max Planck Institut fuer Astrophysik,
Garching; and S. Benetti and A. Harutyunyan, Instituto Nazionale di
Astrofisica, Osservatorio Astronomico di Padova; on behalf of the
European RTN collaboration (cf. IAUC 7987), report that a spectrum
of SN 2005ay (cf. IAUC 8500), obtained on Mar. 29.98 UT by A.
Zurita with the Calar Alto 2.2-m telescope (+ CAFOS; range 340-880
nm), is that of a type-II supernova soon (maybe 8-10 days) after
explosion.  The spectrum is characterized by a blue continuum with
broad P-Cyg features of the hydrogen Balmer series (the expansion
velocity from H_beta is about 9600 km/s).  The He I 587.6-nm P-Cyg
line is also present.
     H. Yamaoka, Kyushu University, writes that K. Itagaki (Teppo-
cho, Yamagata, Japan) found nothing at the location of SN 2005ay
(cf. IAUC 8500) on a CCD image taken on Mar. 19.621 UT (limiting
mag 19.0).


SATELLITES OF JUPITER
     Further to IAUC 8177, the IAU WGPSN has approved the following
new designations and names of satellites of Jupiter:

    Jupiter XXXIX   Hegemone    = S/2003 J 8
    Jupiter XL      Mneme       = S/2003 J 21
    Jupiter XLI     Aoede       = S/2003 J 7
    Jupiter XLII    Thelxinoe   = S/2003 J 22
    Jupiter XLIII   Arche       = S/2002 J 1
    Jupiter XLIV    Kallichore  = S/2003 J 11
    Jupiter XLV     Helike      = S/2003 J 6
    Jupiter XLVI    Carpo       = S/2003 J 20
    Jupiter XLVII   Eukelade    = S/2003 J 1
    Jupiter XLVIII  Cyllene     = S/2003 J 13
