Currently it's Mid Southern Hemisphere Summer - the sun is 85.5 degrees above the horizon at noon for Spirit.

100 sols from now - that figure will be 74 degrees and it will be Early Autumn
200 sols from now - 56 degrees, Mid Autumn
300 sols from now - 50 degrees, Early Winter
400 sols from now - 60 degrees, Mid Winter
500 sols from now - 81 degrees - Early Spring.

Basically it's the 150 to 450 sol's in the future period that will be the worst of it

That's all using the mars24 applet - our resident Purveyor of Whr's might be able to do a better job

In the last weeks, you can see again high dust levels on the sundial (perhaps comparable to pre-storm levels) and also lot of dirt/residuals on solar panels, clearly visible in Sol1355/58 self portraits!

Was the dust storm so violent to bring these smal pieces of rocks over Spirit?

RAT+Array=Bad idea. There are so many ways it could go dreadfully wrong. If there WAS anything that could be done in that way, they would have done it 1200 sols ago when they were at the 300 Whrs level before Larrys Lookout. There is nothing MER could do to dislodge the dust. I can understand the desperation - but it's just a case of holding tight. That's it.
