The σ-capricornids fireball shower
UDC
523.532Abstract
During 2010-2011 years by the Tajikistan fireball network three fireballs were photographed which belong to the σ-Capricornids meteor shower. As a result of astrometric and photometric reductions of the obtained images, the atmospheric trajectories, radiants, velocities, orbits, and light curves of the fireballs, as well as the photometric masses of meteoroids produced these fireballs were determined. Taking into account the observations else six fireballs of this shower in the Canada and USA, the period of shower activity 5-24 July was determined as well as, for the first time, the mean daily radiant drift was found to be Δα =0.6° for the right ascension and Δδ =0.3° for the declination. The coordinates of mean radiant are equal to α =300.4° and δ =-12.4° at the Solar longitude L⊙= 115.6°, which corresponds to the 18 July.
