A preliminary analysis of the fireball track based on detailed analysis of photographs submitted to the BAA Meteor Section and collected by John Mason is shown in the attached picture. This is based on an analysis by Nick James. We are very grateful to the photographers who have provided their images and associated data. Further investigation is underway to accurately determine the height and velocity at various points along the track based on the known exposure times of photographs.

If you have not yet submitted your observations of this event please send them as soon as possible to the Director of the Meteor Section at docjohn@dircon.co.uk or meteor@britastro.org.
