Name: BELFAST.
The place of fall or discovery: Near Belfast, Northern Ireland, Great Britain
Date of fall or discovery: FALL, April 25, 1969, at 21h 25m GMT.
Class and type: STONY, chondrite.
Number of individual specimens: 3.
Total weight: About 8 kg.
Circumstances of the fall or discovery: The fireball was seen all the way from Sussex through London, Doncaster and Yorkshire to Northern Ireland toward Belfast. It was moving from ESE to W NW very rapidly. There was a swishing noise and people reported explosions. The largest fragment of the meteorite weighing 7,400 g was found near the village of Kilrea, Londonderry County. Searches are being conducted.

The British fireball of April 25, 1969
(BOVEDY AND SPRUCEFIELD METEORITES)

This case was chosen for one major reason. It is the only documented case where audible sounds were recorded during a meteor entry (Millman, 1970; Opik, 1970).
In Figure 125 the ground projection of this fireball is shown, along with suitable comments with regard to the audible sound phenomena. The ground area where the tape recording was made was some 30 km away from an area where meteorites were subsequently recovered. In Figures 126 and 127 surface weather maps near the time of fall are shown. In Figure 128 a portion of the tape recording as given by Millman (1970) is shown. The recording was made on a conventional cassette recorder which had a lower frequency cut off of about 30 Hz. In the amplitude versus time plot of Millman, dominant frequencies of 200400 Hz are present. In addition, secondary peaks at 30-50Hz are also present. The recording was made at a point some 40-45 km perpendicular distance from the trajectory. Unfortunately amplitude information could not be obtained for the recording. In addition, the dominant frequency of the disturbance was probably below the cut off frequency of 30 Hz referred to above.
Thus while no theoretical analysis could be performed using this recording, it is by itself an impressive reminder of the great magnitude of certain natural events. The tape is quite impressive and demonstrates the multiple boom aspect of ablating bodies in supersonic flight quite distinctly. It would have been interesting to theoretically obtain a single body interpretation of the source however. In addition to the above effects, the rumbling phenomenon, which according to Wylie 304

It was described as "a lightning flash". Blue, white, green and red lights were seen in the sky and thunderous noises reverberated through the air.
Anyone watching or listening could be forgiven for thinking that something apocalyptic was afoot in Co Londonderry.
But the fireball which blazed above Limavady 40 years ago, was a meteorite, and a very important one at that - this was the 'Bovedy' meteorite, which fell on April 25, 1969 at 9.22pm.

The year 1969 saw several noteworthy events. The first men landed on the moon. Our Northern Irish 'Troubles' began in earnest with the arrival of the British Army on the streets of Belfast and Derry. As a student, I toured the USA that summer. But 1969 saw as well the arrival in our skies of the "Bovedy Meteorite" on 25 April. And this year the Ulster Museum is making the 40th anniversary with a series of lectures given by its meteorite expert, Dr Mike Simms.

Is it a bird?, is it a plane?, no it's a meteorite!
That was the stark conclusion drawn by Ulster folk who witnessed an extraordinary happening over the skies of Northern Ireland 40 years ago today.
On 25 April 1969 the sky literally fell in on the Province and only a select few caught a glimpse of the out-of-this-world occurance.
