My Winjupos measurements on the clearer 22.40UT image, show the spot approx.centred at long 117ｰ and lat -1ｰ-On 10th Oct 21.23UT Marc Delcroix measured a bright spot at longitude 35ｰ(lat +4ｰ)-On 14th Oct 12.24UT Milika and Nicholas measured a bright spot at long 201ｰ(lat +5ｰ) If those two values, 87hrs apart, are for the same spot that would predict adrift of +46ｰ/day and predict a position at my time of observation of 128ｰ not too far from my approx placement of 117ｰ. Latitude is a close match too.
