1/1/2014 8:39:00 AM General There are missing daily files for 01/01/14 because Minimon was off. The buffer was downloaded and there were no tag detections or test tags present, so the buffer file was not uploaded to PTAGIS.

12/31/2013 8:39:00 AM General There are missing daily files during the month of December from 12/13/13 to 12/31/13 because Minimon was off. The buffer was downloaded and there were no tag detections or test tags present, so the buffer file was not uploaded to PTAGIS.
