E. Brown, California Institute of Technology, on behalf of the team at Keck Observatory, reports on IAUC 8636 the discovery of a second satellite of the transneptunian object 2003 EL_61 from images obtained with the Laser Guide Star Adaptive Optics system at the Keck II telescope on Mar. 1, May 27, and June 29. The satellite is about 4.6 magnitudes fainter than the primary. A preliminary circular orbit suggests a 34.1-day period with a semimajor axis of 39300 km, inclined by 40 deg from the larger outer satellite, S/2005 (2003 EL_61) 1. Additional information can be found at website http://www.gps.caltech.edu/~mbrown/2003EL61 SUPERNOVA 2005ky The above designation relates to a supernova of magnitude 22 found during the Supernova Legacy Survey. OCTOBER CAMELOPARDALIDS P. Jenniskens, SETI Institute, reports on CBET 309 the detection of a meteor radiant near the border of Cam and Dra (presumably due to a 1-revolution dust trail of an unknown long period comet), found in video-camera images obtained during Oct.5.712-5.945 UT by J. Moilanen of Finland and others. Of the 19 bright meteors (mag +1 to -6) detected by Moilanen, twelve appeared to radiate from a compact area near RA 164.1, DEC +78.9deg (2000). October 5 was a suspected date of outburst events, due to earlier observations in 1902 by Bailey (1902, Nature 66, 577), in 1942 by Sander (1943, Die Sterne 23, 46) and Teichgraeber (1943, Die Sterne 23, 172), in 1976 by Root (Root 1976, Meteor News 36, 20) and MacKenzie (1980, Solar System Debris, Dover, p. 42).

Only on one previous occasion was the star recorded, this being 2005 May 20 when it was below magnitude 17 (CCD unfiltered) and for which an image can be found at: www.theastronomer.org/vars/2005/euvej0854_20050520_shears.jpg Boris Gaensicke, University of Warwick, adds that this is a polar (AM Herculis star), for which they derive an orbital period of 113.3min. The outburst image of Dec 3 appears on the cover of the December issue of 'The Astronomer' (in press). Guy M Hurst
