R.Chapman, SwRI; and F. Menard, Observatoire de Grenoble, report thediscovery on Aug. 15.6 UT of a satellite of minor planet (130)Elektra from K'- and H-band imaging with the 10-m Keck II Telescope(+ NIRC2/AO adaptive optics system) on Mauna Kea.  On Aug. 15.6417,the satellite was at separation 0".72 (projected separation 1170km) and position angle 70 deg.  The satellite was confirmed by thesame team, also at Keck II, on Aug. 17.6.  The K'-band brightnessdifference is about 8.5 mag, giving an estimated diameter of thesatellite of about 4 km.SUPERNOVA 2003hd IN MCG -04-5-10     M. Hamuy, N. Morrell, and J. Thomas-Osip, CarnegieObservatories, report that a spectrum (range 360-900 nm) of SN2003hd (cf.IAUC 8179), obtained on Aug. 15.28 UT with the LasCampanas Clay 6.5-m telescope (+ LDSS-2), shows it to be a youngtype-II supernova with a blue continuum having incipient H_alphaand H_beta broad P-Cyg lines.COMET C/2003 E1 (NEAT)     Orbital elements from MPC 49276:                    Epoch = 2004 Feb.  5.0 TT     T = 2004 Feb. 13.6332 TT         Peri. = 103.8634     e = 0.763499                     Node  = 137.0688  2000.0     q = 3.245045 AU                  Incl. =  33.5375       a = 13.721077 AU    n = 0.0193920    P =  50.83 yearsCOMET C/2002 Y1 (JUELS-HOLVORCEM)     Total visual magnitude estimates:  July 3.74 UT, 9.0 (D.
