On Sol 2852 (February 1, 2012) the energy production from the solar array was 270 watt-hours, with a Mars atmospheric opacity (Tau) of 0.679, a solar array dust factor of 0.469, with total odometry at 34.36 km (21.35 mi). By March (around Sol 2890), 'Amboy' rock was studied with the MIMOS II Mössbauer spectrometer and the Microscopic Imager, and the amount of Argon gas in the Martian air was measured. The Mars winter solstice passed on March 30, 2012 (Sol 2909) and on April 1 there was a small cleaning event. On Sol 2913 (April 3, 2012) solar array energy production was 321 watt-hours.
