Today’s update, August 20. The storm has reached Regional status and is still growing. Images this morning by Clyde Foster show that dust has reached E. Sinus Sabaeus on the eastern side, while Peter Tickner’s later, daylight, image timed at 08.45 UT shows dust surrounding a still dark Aurorae Sinus to the west, and expanding south west with apparently one discrete dust cloud southeast of Solis Lacus. Dust continues to occupy Chryse and Xanthe. Mare Acidalium to the north is largely unaffected. Other excellent images of the event have been taken by Damian Peach and Eric Sussenbach. Given the expansion to the east, the area remains visible to UK observers, though we must now rely upon others to watch the western side.
