Mars - increased dust activity???

Hi -

I took this image of Mars this morning. Note the bright yellow hue along the western limb (to the right in this image, south is up.) It appears to me that this is possibly an increase in dust activity spreading from the recent storm in Chryse? I am assuming it shows well in this image since it is "side on" instead of "head on", so I was looking through more of the dust at this time.

This image was captured at 0946UT this morning, 08-04-2003. Has anyone else observed this?

Also, note the increase in melting of the S. polar cap.

Jake,

Congratulations on an excellent image of Mars. It appears similar to my drawing made on July 27th. The yellowish haze along the following (morning) limb in your image may
represent dust in the martian atmosphere, especially over the Chryse-Xanthe region. This bears monitoring in the future. The South Polar Cap (SPC) does appear to have shrunk over the last few weeks and we are now noticing the outliers (e.g. Novissima Thyle) more readily.

Please keep up the excellent work!

Very nice picture.

May I ask the details of the equipment used to take the photo?
