The project is preparing to mask off the troubled Bank 7 sector of the Flash file system with a new version of the flight software to be uploaded shortly. On Sols 3928 and 3929 (Feb. 10 and 11, 2015), Opportunity performed some targeted color Panoramic Camera (Pancam) observations. On Sol 3930 (Feb. 12, 2015), the rover drove about 66 feet (20 meters) to get a view into Marathon Valley.

This was followed by a post-drive Navigation Camera (Navcam) panorama. Opportunity drove again on Sol 3932 (Feb. 14, 2015), bumping near a potential surface target. An atmospheric argon measurement with the Alpha Particle X-ray Spectrometer (APXS) was made. On the following two sols a 360-degree Navcam panorama was collected.

A small dust cleaning events occurred on Sol 3934 (Feb. 16, 2015) improving energy production by about 12 percent. On Sol 3935 (Feb. 17, 2015), the robotic arm was used to collect a Microscopic Imager (MI) mosaic of the surface target "Jean Baptiste Charboneau" followed by an APXS placement on the same for a multi-hour integration.

Opportunity drove again on Sol 3936 (Feb. 18, 2015), with a 9.8-meter drive to get a better view into the interior of Marathon Valley.

As of Sol 3936 (Feb. 18, 2015), the solar array energy production was 559 watt-hours with an atmospheric opacity (Tau) of 0.816 and an improved solar array dust factor of 0.695.

Total odometry is 26.13 miles (42.05 kilometers).
