[27 November 2009] The Council for Geoscience is investigating the meteorite of 21st November and is looking for sighting reports. If you have any, please send it to Freddie Roelofse (froelofse AT geoscience DOT org DOT za). The Council is currently in the process of scrutinising data from its seismic network and is eagerly awaiting infrasound data from the CTBTO infrasound stations situated at Tsumeb and Boshof in an attempt to better understand the event and in order to discern if and where the meteor became a meteorite. A detailed account of visual observations will be extremely useful in this regard.
