Seeing good (7-8, Pickering). Transparency 4-4.5m with slight haze. Wind SSE 0-2 kts. No dew.
Altitude = 51-50°.

Note:
Dust cloud in Yaonis has expanded and brightened. Finger of dust now obscuring northern Yoanis and extends into Hellespontus.
Possible spread northeastward into south central Tyrrhenum. Eastern Tyrrhenum, however, is less obscured than on 2 July.
Dust clouds remain bright in green light. In green note bright "swirl" around eastern tip of Tyrrhenum into Hesperia. Little recognizable detail on the floor of Hellas. Violet clearing stronger than on 2 July (2+).
