RADIANTS OF A POSSIBLE METEOR SHOWER BORN BY COMET 1996 B2 HYAKUTAKE The long-period comet 1996 B2 Hyakutake has the following orbital elements (IAU Circular No. 6359, 1996): Epoch = 1996 Apr. 27.0 TT T = 1996 May 1.3965 TT Peri. = 130.2102 e = 0.999662 Node = 188.0430 (2000.0) q = 0.230035 AU Incl. = 124.9098 We have calculated the coordinates of the geocentric radiants of a possible meteor shower for the moment of the closest approach of the Earth's orbit and comet's orbit (March 24, 1996; distance 0.1010 AU) and for the adjoining days. Over the time interval of 8 days (March 20-27) the radiant of meteor shower moved from Centaurus into Lupus. Thus, if meteor bodies exist on the orbit of comet Hyakutake they should be observed in the region of the following radiants: --------------------------------------------------------------- Radiant Date L (deg) R.A. (deg) Decl. V r (AU) 2000.0 2000.0 --------------------------------------------------------------- 1996 March 20.603 0.3182 218.8 -32.2 2.006 0.2340 21.610 1.3182 220.3 -32.8 1.9926 0.1935 22.617 2.3182 221.8 -33.3 1.9782 0.1530 23.625 3.3182 223.4 -33.9 1.9631 0.1175 24.634 4.3182 225.1 -34.4 1.9473 0.1010 25.643 5.3182 226.8 -35.0 1.9309 0.1206 26.653 6.3182 228.6 -35.6 1.9140 0.1713 27.663 7.3182 230.4 -36.2 1.8966 0.2404 --------------------------------------------------------------- There L is the longitude of the Sun, V is the relative velocity of meteor shower (in the units of the Earth orbital velocity), r is the shortest distance between the orbits of the Earth and the comet. This meteor shower could be observed only at low latitudes. If someone observed meteors from the radiants mentioned above, please contact A. Terentjeva: ater@inasan.rssi.ru. A.K. Terentjeva, O.A.
