On August 21 and 22 the storm continued to expand. There is now activity in Hellas as well, so the event continues to be visible from the longitude of the UK. It is unlikely that it will expand much further east than Hellas. On the other side, there is a fresh (and very bright) dust core close to Solis Lacus as of August 22, imaged by Frank Melillo and Gary Walker from the USA. Thanks to all those who have sent data directly to me.
