Rogers" Subject: Jupiter's NEB Hi all, You may be interested to see the attached chart, generated by Hans-Joerg Mettig using JUPOS, tracking the NEBn spots over the last year. Details of JUPOS, and a complete set of recent charts, are available on the web site: http://jupos.org This chart offers a provisional numbering system which we are using for the NEBn spots, as many of the 'barges and portholes' (dark and bright ovals) have persisted for several years. We also note that the NEB is still expanded northward between dark barges B6 (L2 ~ 240) and B1 (L2 ~ 270), and following white oval WS7 (L2 ~ 60). These sectors have never really receded since the complete expansion of the belt in 2000/2001, although other sectors have returned to the usual latitude. Meanwhile on the NEBs edge, the typical dark projections and festoons have largely recovered from their obscurity in 2001. Best wishes, John. 2002 Nov.26 _________________________________ John H.
