Jenniskens, SETI Institute, suggests on CBET 1453 that the steeply inclined (i = 36.3 deg) and intrinsically bright (H = 16.7) minor planet 2008 ED_69 is likely a fragment that remained after formation of the kappa Cygnids, known from its common bright meteors seen in August. J. Vaubaillon (California Institute of Technology) has developed a meteoroid-stream model with ejecting dust in 4000 BC, 2000 BC, and 1 AD from the backward-integrated 38-day orbit of 2008 ED_69, demonstrating that the dispersion of particles in earth orbit is in good agreement with observations if the stream was formed around 4000-1600 BC. THE EDGAR WILSON AWARD 2008 The Smithsonian Astrophysical Observatory announces on IAUC 8962 that the 2008 Edgar Wilson Award for the discovery of comets (cf. IAUC 6936, 8854) is being divided among the following two individuals for the discovery of C/2008 C1: Tao Chen (Suzhou City, Jiangsu province, China) and Xing Gao (Urumqi, Xinjiang province, China). CI CYGNI Guy Hurst, Basingstoke reports a rare outburst of the symbiotic variable star CI Cygni. Visual estimates (0.44-m refl.): 2008 Aug 7.89UT, 11.4; 12.90, 11.3; 22.90, 10.5; 24.88, 10.2 Photometry (V) with the Bradford Robotic Telescope: 2008 Aug 25.97UT, 9.95V (+/-0.05).

The initial observations showed a blue and largely featureless pectrum, but at later epochs several unidentified weak spectral features appeared. Analysis shows it as a type-II supernova with a best-fit redshift of z = 0.206 +/- 0.005. At this redshift, the peak apparent optical magnitude of around 17.8 corresponds to an absolute magnitude of M_V less-than- or-equal-to -22.2, making this object ONE OF THE MOST LUMINOUS SUPERNOVAE EVER OBSERVED.
