Here is a quick process of the last image from the session last night, showing Mars with the terminator projection.  That’s the term that Richard McKim, Director of the BAA Mars Section, used in his report today.  So, I think that’s the most appropriate term to describe this phenomena until we learn more about its nature.

The seeing was very good at times last night, but I chose to process the last image of the session first because that’s when I was most likely to capture the CM (central meridian — the coordinate system we use to identify what part of mars is facing us) where the projection is located.  The projection is indeed still present and looks quite like a “nipple” in this image.

I will update this with additional images from the session (including one that I think was taken in near-perfect seeing) this evening.  Given that we have one more night of possible imaging in the forecast, my plan is to take data first and process later.  So, I may not get to do a complete update on this phenomena until the clouds and rain arrive.

Note the inset shows the terminator projection enlarged 200%, relative to the original image, and slightly enhanced.

Here’s one from earlier.  The terminator projection is barely perceptible coming over the limb.

And finally one from the beginning of the session showing extensive cloudiness across the globe, but taken in excellent seeing.

  1. That Terminal Projection’s source could come from a naturally occurring nuclear fission reactor.

    From Wikipedia:

    Acidalia Planitia is a plain on Mars. It is located between the Tharsis volcanic province and Arabia Terra to the north of Valles Marineris, centered at 46.7°N 338.0°E. The plain contains the famous Cydonia region at the contact with the heavily cratered highland terrain.
    The plain is named after a corresponding albedo feature on a map by Giovanni Schiaparelli, which was in turn named after the mythological fountain of Acidalia.
    It has been hypothesized by J.E.Brandenburg from Orbital Technologies Corp. that a large natural nuclear reactor in the northern Mare Acidalium, near the large, shallow depression north of Acidalia Colles (similar to Oklo on Earth) underwent catastrophic meltdown.

    Plasma physicist John Brandenburg has detected anomalies in gamma ray emissions from Mars in data from the NASA Mars Odyssey orbiter. This points to an abundance of radioactive uranium, thorium and potassium, especially in one particular spot on Mars that indicates that there was once a thick layer of radioactive substances, and the likelihood of a natural reactor.
