Hi All,

I have attached a couple of images of the two great sunspot groups. We'll have to put aluminum foil on our heads for the next couple of days!

Best,

Hi All,

The Martian subearth and subsolar points are now within one degree of one another. This means that for the next couple of weeks conditions are favorable for specular reflections from ice crystal clouds or surface frosts. These would be most likely to appear in the high southern latitudes -- 20-25S. -- and east of the central meridian.

Good hunting!

Best,
