Saturn May 14th +63 anticyclone

Hi All,

Imaged Saturn May 14th in good seeing but the session was curtailed by the arrival of a considerable amount of cloud, sort of out of nowhere.

My 742nm IR data clearly resolves the approx +63 dark spot (anticyclone) that has been there since at least Jan 22nd.

Have attached a couple of animations that really do highlight the movement of the dark spot over 34 minutes of Saturn rotation.

Regards
Trevor
