Note:
Significant changes have occurred over the past 24 hours:
  1. Mare Tyrrhenum, Syrtis Minor, and Crocea-Oenotria have lightened considerably, appearing to be covered by a thin whitish cloud.
  This is similar to the aspect of Mars in 2001 about a week before the great dust storm. These features were dark and "normal" on 30 June (Beish) and throughout June (Grafton, Parker, Lazorotti, Pellier).
  2. Bright ochre spots rimming Hellas and obscuring Deltoton-Iapygia -- the latter spots are conspicuous in green light. Hellas spots imaged by Grafton on 6/28. Little detail noted on the floor of Hellas.
  3. Possible small dust cloud over SPC. This has been imaged over the past week by Bates, Lazorotti, Ng, Pellier, Williamson, and others.

Rima Australis-Ulyxis Fr. prominent. NP Hood thinner as is AM limb arc. Violet Clearing partial (2+) in areas not covered by clouds that are faint in blue light.

PARKER uses a 41 cm Newtonian working at f/55 with an eyepiece projection together with an SBIG ST9XE ccd camera, equipped with a CFW-8C filter wheel and RGB interference filters
