Opportunity is at the base of "Solander Point" on the rim of Endeavour Crater.
The rover is positioned in front of a large rock, called "Tick Bush" for in-situ (contact) investigation with the instruments on the robotic arm.
On Sol 3392 (Aug. 8, 2013), a Microscopic Imager (MI) mosaic was collected of Tick Bush, followed by the placement of the Alpha Particle X-ray Spectrometer (APXS) for multi-sol integration.
On Sol 3396 (Aug. 12, 2013), the robotic arm repositioned the APXS with a small offset, documented by a Microscopic Imager finder frame image.
Also on that sol, the rover took advantage of a celestial alignment and imaged the transit of both moons, Phobos and Deimos.
A second Phobos transit was imaged on the next sol while the APXS continued to integrate on the rock target.
As of Sol 3397 (Aug. 13, 2013), the solar array energy production was 376 watt-hours with an atmospheric opacity (Tau) of 0.695 and a solar array dust factor of 0.532.
Total odometry is 23.73 miles (38.18 kilometers).
