Here's what the mostly-far-side of the sun looked like a couple of weeks ago - this is an average of 8 2x-zoomed and registered MR frames ("poor man's superres") from sol 363, followed by a contrast stretch:
A Phobos transit was just starting and ending in these 8 frames - that explains the shadowy notches at 7 and 10 o'clock. But a couple of sunspots are clearly visible. |

...But a couple of sunspots are clearly visible. Sol 363 raw image, subframe stretched by histogram, then hipass-filtered with radius 5, result brightness stretched: Edit: Same with this Sol 368 image: to improve evidence, that it's not an artifact. Probable sunspots moved to the right and weakened. |
