Comments:
Hart15M has completed R4869.
Sources between 325-1150a and 325-1206b were missed due to antenna drive failure following a local power brownout of unknown origin.
Weather conditions were clear at the start, 50% cloud (cirrostratus) in the middle and mostly clear at the end.
Data will be e-shipped to Washington.
