I've been keeping an eye on the sundial images looking for signs of a cleaning event. I've noticed some changes in the latest to be downloaded although they may be due to changes in the lighting.

A : clean patch at top of circle streak at bottom
B : increased contrast from dust left behind next to mirror
C : clean patch next to wire

Also note the missing clumps of dust on the deck

A broader view show a contrast between sol 1221 and 1227

Has anyone heard if there has been a change in the power levels?
