BRIGHT FIREBALL ON 27 AUGUST 2012

Reports are coming in of a bright fireball, visible at about 23:15 BST
(22:15 UT) on Bank Holiday Monday, 27th August 2012. That night the skies
were clear over many parts of the UK and the waxing gibbous Moon was 
shining brightly in the southern sky.

Travelling south on the A1 north of Alnwick in Northumberland, Gary
Broughton reported that the fireball was green with an orange tail and that
it descended almost vertically from his viewpoint with the Moon clearly
visible about 5 degrees to left (east) of the fireball.

>From Croesyceiliog in Cwmbran, Debra White saw the fireball towards the
north-east as brilliant white, tailing off to green and orange. Also in
Wales, from Caerleon, near Newport, Jeff Preston (looking roughly
north-east) reported that the fireball was approximately ten times brighter
than Venus and began in the north-west at about 60 degrees elevation,
descending to about 40 degrees elevation in the east-north-east, passing
left to right below the "W" of Cassiopeia.  He estimated the duration as
about 3 seconds and reported that he head a distinct "boom" long after the
fireball.

Clearly this was a major fireball event and any BAA members who saw it, or
who may have been contacted by non-astronomers who witnessed it, are asked
to collect as much information about the sighting as possible and send it
either to the BAA Meteor Section's Fireball Co-ordinator Len Entwisle at
len.entwisle at btinternet.com or to meteor at britastro.org.

Useful information will include the name and location of the observer, the
precise time of the event, the altitude and azimuth of the start and end
points of the visible track, the position of the observed track against the
background stars (or in relation to the waxing gibbous Moon and Mars in the
sky, if seen towards the south-east), and a description of the fireball's
visual appearance, colour, etc. together with any unusual features.
