I'm assuming that these are clouds?

yup, and very early in the morning as well ,9:24:42 mars LST

here's sol 291, around the same time of morning as the previous image, with more clouds :

There must be something conducive about that time of day for them to form, I don't believe this level of distinction in the clouds has been seen at other times of day. (though, to be fair, none have been seen with this level of distinction period)

Superb cloud pictures. Have to agree that atmosperic conditions must be favaourable for cloud formation around dawn.

? Rising sun warming air and causing thermal with an inversion cooling to dew point ? Where are our resident weather experts :D

I hope this will be a chance for them to get them too. There will be issues with the clouds moving between frames (those L7's take a long time to expose) but that'll be manageable.
I can understand them not wanting to waste that many frames on what may not be there, since they can't see the clouds then choose immediately to take a full filter series of them. But this is 2 sols in a row at a certain time of day that had them, so some morning in the near future they might have a great chance of getting their first good color shot of clouds.

Sorry - I'm not nearly as familiar with Martian weather as Earthtian ( :D ) weather.
