There was MODIS data loss on 271 from 17:47:27 to 18:30:49. The ground track at the time began in the southern Indian Ocean continuing north over Afghanistan and Russia towards the North Pole.
Terra MODIS experienced an non-recoverable data loss on 2011/211 07:31:49 - 07:41:03 (07/30/11) due to an SFE Anomaly.
Terra MODIS experienced a non-recoverable data loss on 07/21/11 due to contact errors.
The time period of loss is 2011/202 13:24:02-13:24:24
Terra MODIS performed a successful lunar calibration on 07/19/11 (2011/200 22:52:24-22:59:10).
Spacecraft roll of -6.9706 degrees with a phase angle of 55.33 degrees.
Loss of pointing accuracy times for this event were 20011/200 from 21:27:00-23:11:26.
Aqua MODIS performed a successful lunar calibration on 07/10/11 (2011/191 21:25:33-21:32:19).
Spacecraft roll of -20.0 degrees with a phase angle of 55.81 degrees.

MODIS Characterization Support Team
The MODIS Characterization Support Team (MCST) is dedicated to the production of a high quality MODIS calibration product. This product is a precursor to every geophysical science product. MCST works for the Science Team Leader and is responsible for developing and maintaining the calibration product (L1B algorithm).
Collection 6 has been under development for a number of years. MCST, in consultation with representatives of the science disciplines, developed improvements to the calibration algorithms and methodolgies to handle known issues with the aging MODIS sensors. Summary talks of the proposed Collection 6 changes have been delivered at the MODIS science team meetings over the last few years.
Current L1B LUT Versions:
Terra C6: 18.104.22.168; Terra C6.1: 22.214.171.124; Aqua C6: 126.96.36.199; Aqua C6.1: 188.8.131.52
