This spot moves rapidly eastward in System III (as expected). See graph w_29S.jpg The second spot at -42 deg moves westward slowly (also as expected, see graph w_42S.jpg), and it is in the place where last year convective spots formed. The last image by Ed Grafton (Oct. 19) show appatently small dark spots in temperate - tropical latitudes similar to those captured by HST last apparition, but they must be confirmed by their rotation observation. The image also shows features in the Equatorial Zone. These are very important to confirm the drop in the equatorial jet observed between 1996-2002. Good observations!
