Targeted the far North dark spots this morning. Have again captured the spot at approx +63 degrees.
The spot that I imaged March 3rd that was on the Southern edge of the dark collar of material surrounding the hex seems to be drifting at quite some rate. I see that the zonal wind velocity at +63 is approx 60 m/s. March 3rd it was at approx Lat 62.4 L3 44,6 This morning, March 7th it was at approx Lat 62.7 L3 352.5 so has drifted 52 degrees in 4 days.
The dark spot is best seen in my IR data set from March 7th 18:04 UTC where it is just to the F side of the CM. I have attached an animation to this message, it is 4 frames over 1 hr 23 min's, the dark spot can be seen quite readily in the animation.
