I had a look this evening 3rd july on Mars with the 100mm refractor and
240x with average images,good at the beginning.

The patch on Lybia and Isidis Regio was seen clearly,but not one formation
but two formations near the limb.

There was bright yellow-ocre color. Syrtis Major was clearly defined and
contrasty,seemed normal.

Difficult to say if the yellow patches extended away the limb.

This is confirmed as a dust event,stormy.

Strange to see quite different results when comparing with the 29th june
observations (indeed S.M. was at limb).

The yellow patches were captured without filter,with W12 and RG435 blue,
filters .
I noted also that the overall disk color gave a yellowish tint of the
planet (naked eye too): noted yellowish orange light.
That's make a certain time with dusty atmosphere well noted.
This could the source of certain mechanism.

Only 14° alt., low in the southwest. Some detail visible with my 222mm dobsonian.
