More Sunspots emerging from the Northeastern limb of our Star - Sun.
Active region AR2993-2994 have produced X1 class of flare already, thankfully towards the farside of the Sun, but now that they're here facing Earth, one can only imagine the activity in coming days.
And more are on there way! Solar Cycle 25 is proving to be strong, do find time to see these with proper Solar Filter and with proper hydration.
