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 http://207.7.139.5/mars/spirit/navcam/2007...I4P0165L0M1.JPG http://207.7.139.5/mars/spirit/navcam/2007...00P1914L0M1.JPG Has anyone heard if there has been a change in the power levels? |

Yes - cleaning is usually thought to be due to high winds
Dust storms are thought to cause high winds Thus - major cleaning and dust storms tend to be closely related. Maybe it's something to do with the change in illumination - BUT - Opportunity looks utterly A1 clean right now. Doug |
