(meteorobs) Large scatter event 21 March over OK/TX - anyone see anything?

Thanks, Pat.  Based on all the events I've recorded since mid-Feb, this APPEARS to have been a large object - or at least big enough to have a clean doppler scatter until disentegration.  The line is very common with satellites, and the spreaded spectrum is an exact match with other hits disintegrating inside the main beam.  But I've never seen two at the same time.

I am about 60 miles SE of the Kickapoo transmitter.
I was outside playing volleyball at the time and I saw or heard nothing.
