The sun gives us lots of unexpected.
Had been looking sun since 1975.....occasional then, to today.... the last 33 years.
This forth cycle is one with lots of unexpected.
The starts itself lacks activities, and in Ha lacks prominence activities...... Big high prominances.
Of course, these will definitely affect our weather.
Interesting to see if we enter the mandal? cycle....... the cycle of prolong no activities on the sun. Lets see.
The sun is full of surprises.

Today (19 Oct 2020), minor B-Class flares were spotted in H-Alpha. Saw the sunspot (2776) in all 3 colours -White light, Calcium-K and H-Alpha. A slow start to Cycle 25 and yes, agree that the Sun is dynamic and full of surprise even at this early stage of the new cycle.

Hi Alfred
Your camera superb and definitely able to photograph double stacked view of solar activities. Nice photos.
On the single stack, those brighter regions are not visible. Pls keep sharing. Thanks.

Today, look at the sun in both single and double stack..... Double stack in pst and single stack with lunt 35mm.
On the double stack, clear prominence at both east and west edge of the sun, while in single stack, only the western one showed up. As for the sunspot(now only 1 region only) the single stack only showed a small dot, whereas in double stack, a bright c shaped bright region can be seen.(below that dot)
As to the lightbridge described by spaceweather, the scopes i have were unable to achieves such magnifications. Will work on that, but doubt so because it probably involve software that cancel atmospheric turbulence.
