Neptune on 15th Oct in steadier conditions than 12th. Bright equatorial spot at a similar location on disc as the 12th even though the CM is very different. Calculating a drift of +49deg/day for this spot. Possible second spot near centre of disc identified in gif animation. See separate post for positions
Cheers,
Martin
