July 30th, 2015 – The Moshampa Fall

Just about a month after the FameninĀ fall, a startling event occurred a couple of hundred km to the north. At about 20:10 local time, a large fireball was observed by many peopleĀ to rip across the sky, leaving a dust cloud in its wake and meteorites (at least one, anyway) on the ground. The event was reported to have at least 4 bursts (we’ve confirmed this on infrasound data) and the sonic booms were heard and felt by many across the region. In the towns closest to the fall, witnesses reported windows breaking and the ground shaking. Very exciting for thousands of witnesses!


One of the people who witnessed the event was a farmer standing at the edge of one of his fields. As he watched the fireball burst, he reached for his phone to take a picture but was, unfortunately, too late. He then heard the sonic booms and, finally, a ‘sjoop!’ noise. This last noise is, apparently, the sound that a meteorite makes as it buries itself in your moist field because that’s what he found – a 2kg meteorite buried in his field. After hearing the ‘sjoop,’ he went over to investigate a fresh pit that had appeared in his field not too far away from where he was standing. After a bit of digging, there it was. The fourth meteorite documented to fall in Iran.

Upon initial analysis, the stone appears to be an LL chondrite. It is only very weakly magnetic and has, on average, large chondrules. On a broken section, the chondrules are quite distinct leading us to believe that it is of a low petrographic grade. Possibly a 4.
