Opportunity has officially left Marathon Valley.
On Sol 4482 (Sept. 1, 2016), we approached the 'Lewis and Clark Gap' and with the successful drive on Sol 4484 (Sept. 3, 2016) we passed through and are now on a course that will take us into Endeavour Crater.
Regional dust storms are beginning to occur in our general vicinity leading to higher general atmospheric opacity (tau), but Opportunity has not yet experienced any storm activity directly.
As of Sol 4486 (Sept. 5, 2016), the solar array energy production is 476 watt-hours with an atmospheric opacity (Tau) of 0.957 and a solar array dust factor of 0.675.
Total odometry is 26.88 miles (43.26 kilometers).
