Saturn July 13th dark polar spot + bright EZ spot

Imaged Saturn tonight July 13th targeting the +63 spot. The ephemeris I circulated recently based on a L3 drift of -11.4 deg/day is proving quite accurate. The prediction was for an L3 285 and at the CM 12:58 UTC. I have 4 data sets at approx 20 min intervals covering 60 min's of rotation from 11:53 through to 12:54. I have the +63 spot in all data sets, interestingly I measure it to now be at +64.8.

Of further interest all data sets also have the bright EZ spot. I measure it to be at Lat +7.3 L1 52.8 & L3 259.4

All data was 685nm IR, also did a set of polar projections. The polar dark spot is well seen as is the bright EZ spot, even in the polar projection animation.
