Titan's Arrow Storm

Titan's Arrow Storm
Titan's Arrow Storm A huge arrow-shaped storm blows across the equatorial region of Titan in this Cassini photo. The photo was taken on September 27, 2010; that image was truncated in the south, so a small portion of the disk below the storm was filled in with an image from July 9, 2010. This storm created large effects in the form of dark -- likely wet -- areas on the surface of the moon, visible in later images. NASA / JPL / SSI

After this storm dissipated, Cassini observed significant changes on Titan's surface at the southern boundary of the dune field named Belet. Those changes covered an area of 500,000 square kilometers, or roughly the combined areas of Arizona and Utah. The part of the storm that is visible here measures 1,200 kilometers in length east-to-west. The wings of the storm that trail off to the northwest and southwest from the easternmost point of the storm are each 1,500 kilometers long.
