Mars 2018-06-13: Dust storm shoots through Valles Marineris

Now as seen on Sky & Telescope's web site - Sean graciously used my image in his article!

Sky & Telescope: Observe Changes on Mars

=========================================

I've just started processing around 40 mins of data I grabbed for Mars last night, and have noticed what looks like an area of the current dust storm extending around the equator in a meandering line. It's apparent in three separate images I've checked so far, so I don't think it's an artefact.

Is this really an off-shoot of the dust storm, or something else? How would I check/confirm? (Still pretty new to all this!)

Image was taken at UT 19:18, 2018-06-13 @ approx. 1°18'N 103°54'E

EDIT:

Turns out this is the dust storm making its way through Valles Marineris.

Thanks to Sean Walker from Sky & Telescope (via Cloudy Nights) for identifying what I'd captured!

EDIT 2:

Revision E is an image taken later in the morning, with the feature of interest rotated further into view. Processing was improved to manage the Gibbs artefact better.

If I'm not mistaken, Pavonis Mons and Ascraeus Mons are also made visible by the dust lane running between them (after exiting Valles Marineris?).

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
