Opportunity is positioned on the north end of Cape York on the rim of Endeavour Crater with an approximate 15-degree northerly tilt for favorable solar energy production.
Opportunity is conducting regular radio Doppler tracking measurements, in-situ (contact) science investigations of the target, "Amboy" and continues to collect the 13-filter, 360-degree "Greeley" panorama.
On Sol 2833 (Jan. 12, 2012), the robotic arm performed a tool change to place the Alpha Particle X-ray Spectrometer (APXS) on a repositioned Amboy target. With multi-sol APXS integration ongoing, several opportunities were used to perform Moessbauer spectrometer temperature diagnostics.
The diagnostic tests help to establish the best temperature range of operation for the Moessbauer, which exhibits some temperature-related anomalous behavior. In addition to the continued radio Doppler tracking, panorama collection and in-situ science, in the plan ahead regular Microscopic Imager (MI) mosaics will be collected of an extended area around the in-situ targets.
As of Sol 2838 (Jan. 17, 2012), solar array energy production was 276 watt-hours with an atmospheric opacity (Tau) of 0.602 and a solar array dust factor of 0.447.
