Colleen has made superb progress and we should soon be able to offer estimates for the total mass that falls in any given meteorite fall, the percent that is actually recovered, and possibly provide some insight on the type of meteorite that falls from its radar behavior (maybe!). To do these things, we need to calculate the mass of meteorites seen in previous meteorite falls, and to that we need accurate time stamps for the fireball terminus (e.g. The point when a meteor goes dark). Terminus altitudes are useful too, but we really need the times as accurately as possible. Of the meteorite falls Colleen is working on, we don?t have an accurate time stamp for the following ones. Could I ask y?all to dig into your videos and notes for these events and look for terminus times? We will produce a paper and make it available, and should be able to estimate the total mass reaching the ground for future meteorite falls.
