[ Tvashtar was discovered in IRTF images in November 26 1999, several hours after a Galileo flyby. Images taken with the ESO 3.6m telescope and its adaptive optics in September 1999 revealed the presence of faint hot spot (labeled 990930D). The outburst was studied by the Galileo spacecraft over several years. During this time, a long, high curtain of lava was seen to erupt from one ]patera
