Draconids 2005, visual

An outburst of Draconid activity was observed from
Asian and eastern European geographical longitudes
on October 8, 2005. The activity was also observed
by radar technique with highest rates at a solar
longitude of 195.44 (2005 October 8, 17h UT). With
a population index of r=3.0, an equivalent ZHR near
150 was derived (Campbell-Brown et al., Univ. of
Western Ontario). Visual rates may be lower due to
the different range of larger masses causing visual
meteors.

Solar longitudes refer to equinox J2000.0. ZHRs were computed with a population index of 3.0 in accordance with the radar ZHRs. No personal perception coefficients and no additional zenith correction apart from sin(hR) are applied.
