Following an earlier prediction by E. Lyytinen and T. van Flandern (2000, EMP 82-83, 149), P. Jenniskens (SETI Institute) notes that the earth should encounter the 1932 dust trail of comet 55P/Tempel-Tuttle on Nov. 18d23h03m UT, according to J. Vaubaillon (California Institute of Technology). Meteors would radiate from R.A. = 154.0 deg, Decl. = +21.4 deg, at a geocentric speed of 70.9 km/s, according to I. Sato (Tokyo, Japan). M. Maslov (Novosibirsk, Russia) calculates a peak time of Nov. 18d23h05m, a shower width of FWHM about 5 hr, and a peak rate of ZHR about 60/hr, mostly due to small meteoroids. E. Lyytinen (Helsinki, Finland) predicts the peak time to be earlier at Nov. 18d22h36m. This outburst will be best seen from China, India, and parts of Russia. The trail encounter is similar to that of 2006, when the 1932 dust trail was also encountered far from the position of the comet (cf. CBET 767).
