We will follow the Mercury transit with the SST (as November weather permits). There will be a live Youtube feed, which starts around 12:00 UT (13:00 Swedish time). The transit starts around 12:35 UT (13:35 Swedish).

Update: We show two good CHROMIS images from the transit. The upper one is a continuum image at 400 nm, showing Mercury with a background of photospheric granulation. The bottom image is from the nearby chromospheric Ca II K line. Click on the image to see it in full resolution.
