Meteor Section

The Meteor Section of the British Astronomical Association encourages amateurs to become involved in meteor astronomy through active observation, Section meetings, and contributions to the Section Newsletter and other publications of the Association.

Occasional reports are published in the Journal of the BAA. An account of the activity of the Section each year can be found in the Report of the Meteor Section, part of the Association's Annual Report.

DRACONID METEOR OUTBURST OBSERVED

Observations by BAA members and by non-members who have so far communicated with the Director of the Meteor Section confirm that a short-lived outburst of Draconid meteors occurred on 2011 October 8.

Draconid rates were generally low until around 1900 UT on October 8 when a rapid increase in activity occurred, peaking between 2005 and 2015 UT. Thereafter there was a rapid decline, with Draconid meteor rates returning to a low level by 2130 UT.  A very preliminary analysis of visual observations made by a group of observers led by the Director, observing from near Goreme in central Turkey, indicates that the peak equivalent ZHR was about 350 m/h between 2005 and 2015 UT, although correction factors are high due to the effect of bright moonlight.  It is possible that lesser, short-lived secondary bursts in Draconid activity were also noted around 1915 and 1938 UT.

Observers in the UK had to contend with cloud and rain on the evening of October 8, but it is extremely encouraging that so many individuals and local society groups battled the elements in the hope of getting a view of the shower.  Some were rewarded for their persistence.  A short period of partially clear weather enabled observers in Dorset, Wiltshire, Oxfordshire, Gloucestershire and Berkshire (and hopefully other areas as well) to glimpse the shower between 1955 and 2030 UT.  By a fortunate circumstance this was coincident with the main peak in Draconid activity.
