''sol 47 ends at 2:10 p.m. on Friday, [[2004]] [[March 12]] PST''

On sol 47, which ended at 2:10 p.m. PST on Friday March 12, Opportunity
awoke to "No Particular Place to Go" by [[Chuck Berry]] in recognition of the
stay at "Berry Bowl." Engineers also played "That's Amore" by [[Dean Martin]]
in honor of the 
moon [[transit of Phobos from Mars|Phobos moon's transit across the skySun]]. 

Opportunity finished remnants of activities from the past sol's research at
"Berry Bowl." The sol started with the hazard avoidance camera taking a
picture of the "Berry Bowl" area as a context picture. The miniature thermal
emission spectrometer then performed some "sky stares" of the
atmosphere. At 11:30 Local Solar Time, the robotic arm started moving. It
picked up the alpha particle X-ray spectrometer and moved to a new
location nearby, then switched to the Moessbauer spectrometer. Both
spectrometers are searching for clues about the chemical composition of
the mysterious "blueberries."

Later, Opportunity took panoramic camera images of the suite magnet on
the rover itself, which is collecting atmospheric dust samples to understand
why the martian dust is so magnetic. The panoramic camera also took
images of a target dubbed "Fool's Silver," which contains an interesting
angular feature in the outcrop.

After all the morning's hard work, Opportunity took a short siesta to rest
and recharge. Opportunity reawakened a few hours later to take more
images of the atmosphere with the miniature thermal emission
spectrometer and panoramic camera. Those were taken in the same
locations as the morning measurements to compare the atmospheric data
throughout the sol.

At 15:40 Local Solar Time, Opportunity took about a dozen images of the
Sun to catch the [[transit of Phobos from Mars|eclipse by the martian moon, Phobos]]. Opportunity once
again shut down for a nap and woke up at 4:53 Local Solar Time, sol 48,
for a tool change and a communications session with the Odyssey orbiter.
While the rover was awake for the Odyssey pass, the rover heated up the
robotic arm, which had chilled to almost -80 degrees Celsius (-112
degrees Fahrenheit). The motors cannot move at that frigid temperature,
so the rover arm heated for 32 minutes to surpass the operational
