The Sun 06/25/2017 @ 20:30 UT

These images were taken with a PST-DS and Mallincam DS2.3+. Stacking and wavelet in RegiStax and final processing in Photoshop.

The Sun continues to be quiet as it moves towards what seems to be a deep minimum, but this image shows two active areas, AR2664 towards the center of the disk, and  AR2662, the lighter area at the top of the image. Neither is likely to cause flares. I've also included a couple of lightly-processed monochrome images for comparison. A small, "hedgerow" type prominence is visible close to AR2662. I've included a cropped image of it.
