Shiny rock coating close-up (Sol 1304)

This shot was taken by the arm-mounted WATSON camera at 10:46 PM local time, illuminated by the LED (see also shots lit from the left and right, for perspective). The boulder Percy is analyzing (see here for a daylight view) isn't as reflective as some near the rover, but then again, this part of the Jezero rim seems to have more than enough funky rock coatings for anyone!
