Wed, 12 Mar 2014 - Morning twilight fireball at 06:13 GMT on Mar 12
There were numerous reports of a bright fireball seen at 06:13 GMT in the bright pre-sunrise twilight of Wednesday 12th March.
Early reports to the SPA Meteor section were submitted by Paul Wallace (near Dumfries) and Kevin Boyle (Stoke on Trent). There are also additional reports from Manchester (two reports), Wigan, Llandudno, Holmes Chapel (Cheshire), Moorsholm (N Yorkshire), Cumbria, Prestwick and Portpatrick. Later reports, in most cases reported to the Armagh Fireball website, included those from eyewitnesses in Fife, Edinburgh, Glasgow, Dublin, Limerick, Preston, south Wales, Devon and Northern Ireland.
From near Dumfries, the fireball was seen to cross the west to south western sky, whereas it was in the western sky as seen from Stoke and in the WSW ("over Anglesey") from Llandudno. Cloud cover will have limited the number of eyewitnesses from south if the fireball's track. However, a report from Jason Bates from near Newport, south Wales placed the fireball in the direction of the Brecon Beacons (i.e. in his north western sky)
Taking these together, the most likely atmospheric trajectory would seem to be over the Irish Sea between Ireland and North Wales.
If images were available from the automated cameras that monitor for fireballs, then it would be possible to tie down the trajectory more accurately. However, these cameras operate during the hours of darkness and so few are likely to have still been operating this far into the morning twilight. William Stewart has reported thaty although some of the NEMETODE cameras were still operating and the fireball would probably have been in their field of view, a combination of mist and the bright twilight prevented thenm from recording it.
The duration of the fireball seems to have been 2-3 seconds. Both Paul and Kevin mention its green colour. Some other reports also mention a blue colour.
As is often the case, there are a wide range of directions of travel quoted for the fireball, but the most frequently quoted directions suggest that it was travelling roughly west to east. Several of the reports commented that the fireball was travelling down to the horizon at a steep angle. In somer cases, this led the witnesses to believe that it had come down nearby.
