Thanks, Masatsugu,

 

It is getting warmer here, too, but for us that just means mosquitoes! I agree about the processing. I have started using a new technique as of today -- I am still on a learning curve with the new ST9XE and am getting a bit old to climb those learning curves any more!

 

 I agree that the albedo features are a bit muted visually, but I try to process to bring out fine details whenever possible. Earlier this month, April 14-16, there was fairly strong blue clearing both visually and on the CCD images. It is no longer apparent. The SPC has broken through with the "Lifesaver Effect" appearing as you describe.

 

  Hope we keep the dust away for a while!   Best,

 Here are some Mars images from 28 April. Note the tiny terminator cloud over Olympus Mons and the streak running parallel to Cimmerium and Sirenum. This has been observed fro several apparitions and is especially conspicuous near quadrature.

© . . . . . . .Here are some belated Mars images from 4 May. Note the strong appearance of the "W" clouds in Tharsis: Spring has sprung on Mars and the birdies are chirping!

Subject: RE: Initial Mars 22nd May UT

 

Dear Masatsugu,

Many thanks for the alert regarding dust in Thaumasia. You, Valimberti, Kumamori, and Ng have done beautiful and prompt work. Even though it would be most interesting, let's hope this doesn't go global!! I'll send out a message to the Marsgroups and ALPO.

 Best,
