Kann denn jemand mal zusammenzählen, wieviel Gramm jetzt schon gefunden wurden?
I was going back through the radar data in preparation for writing an abstract on this fall for the upcoming Meteoritical Society meeting, and I made a discovery. One radar sweep with meteorite signatures was overlooked! [...]Now we see that some of the objects in there are moving towards the radar (red blips). Those aren’t noise; they’re falling meteorites. We can add this set of radar returns to our stable of usable data. It turns out that the meteorites seen in these returns extend farther to the east than the previously noted radar signatures, extending the strewn field out beyond Coloma a bit.[...]With these two “new” radar returns, the picture becomes clearer. Between these and the fact that most of the meteorite finds are occurring somewhat north of the calculated strewn field centerline, I’m going to move the projected strewn field. My suspicion is that the wind strength decreased between the time of the fall and the time of the weather balloon launch, so the strewn field I calculated was offset to the south from the actual one.[...]Note how the radar returns cover an area that extends slightly more to the north and east than the calculated strewn field. Those radar returns farthest to the east appear later than the others, indicating that they are probably smaller in size that the others. But not necessarily; separate detonation events along the meteor’s path complicate that conclusion.
UPDATE (19 May 2012): With my final (?) summary of the radar data as posted on the main page for this event, and with feedback in the form of meteorite locations, I’ve moved the projected strewn field slightly north and extended it out further to the east a bit.Here’s the entire strewn field. The projection for large masses out to the west is unchanged. Bear in mind that any multi-kg meteorites that landed over there would most likely embed themselves in the ground, and the rains may have erased their burial pit. It would be difficult to find anything over there, but if you do you get to be a Meteorite Hero.
Collected hands free and properly documented on 4/27/2012 just hours after the rain. After this specimen dried out it began to show more and more fractures. Specimen will be studied non destructively.
