AR 2757 survived it's trip to the center of the Sun.
At high mag, you can see the umbra and penumbra of the primary spot as well as smaller "pores".
There is another active region developing near the Sun's SE limb. With a solar filter you can make out the whitish "plage"; areas that are much hotter than the surrounding chromosphere.
Other than that, it's just another day.
