In white light AR2670 is now well onto the disc and is a modest bipolar group amid extensive faculae. The main spot displays the Wilson effect but otherwise looks fairly featureless. The smaller component is similarly quiescent.

Polar faculae are once again quite conspicuous in both hemispheres.

In H-alpha I had to do a lot of cloud dodging so optimal tuning was difficult. However AR2670, with its fringes of plage sits in a complex bipolar magnetic region that is clearly footed in the southern hemisphere but which has north-reaching extensions, possibly as far as the equator.

Otherwise the magnetic regions spanning the northern half disc are not particularly well defined.

A short dark filament is visible in the SW quadrant in a BMR that otherwise currently shows no activity in white light. A shorter filament is approaching the SW limb at high latitude.
A small prominence is visible on the SE limb and there was a bigger, much fainter cloud on the SW limb, near the filament, but this is hardly visible in this processed image.
