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.
