The table of contents for the October 2008 issue of Icarus is now online. Included in this issue is "Galileo observations of volcanic plumes on Io" by Paul Geissler and Michelle McMillan. Geissler and McMillan describe the observations of Io's volcanic plumes as observed by Galileo, and look into the differences in appearance between the gas plumes observed in eclipse and the dust component observed in daylight. The paper was posted online in about four months, and yes, I still intend on doing a full post on that paper.
