Hi Larry,

Are these the products you are looking for?  I ask because I'm not
familiar with these products.

The date that you mentioned above is about the time the new NEXRAD
products started coming in.  They started appearing on 11/27.  I'm
wondering if that might have had an impact on the filing of products on
your machine.  Are you filing radar products?  If so, the increase might
have caused pqact to get behind.
