Solar cycle 25

[superiorstream]

Sun today
3004 is a sunspot with lots of crack like bright streak And
Now both the northern and southern belt are filled up with filaments. All are long and one is especially fat. Pls use a double stack Ha filter.
Do take a look.

Hi All
Some had wondered why l stop observation of the sun.......no l didn't but stop posting because l observed that those descriptions can easily be seen at solar and heliosp observatory site on spaceweather.com. So no point duplication.
However what's not indicated there is the prominence and filaments situation on the sun.
Hence l will still observe with the DOUBLE STACK and indicate when the filaments and prominence become interesting.
So still happy observing.

Hi All interested in the sun
As normal take a look at the sun early morning in Ha double stack.....for normal descriptions in ha,cak,540nm you can look at spaceweather.com.
Now the filaments situation
Almost the whole of the northern belt filled with filaments. Even regions above the belt in the north got quite some.
Half the southern belt are active,but no long filaments.
As for prominence
Relatively short prominence and more in the north than the south.

Hi All interested in solar
Want to draw your attention to a photo posted on spaceweather.com on the 12 Dec 2022.
It summarise the sunspot whitelight image for the year 2021 and 2022.
As l had said most of the sunspot are small when compared to the previous cycle of 24.
Does that mean a difference in solar outputs? or particles emited from the sun?

Hi All Interested in solar obs
Today...just at 920am a huge prominence flare up at the edge where sunspot 3668 is heading....
It's shape like 2 huge tree spreading out at the top and it's 2 huge trunk resting on the sun.
Shape wise it's as big as 3668 and 3664 put together. Really huge.
Do take a look....the biggest l see in this cycle.

I saw the giant sunspot yesterday through a pair of binoculars. Very impressive. Haven't had a chance to observe in H-alpha yet.

Yes,you got to see it in Ha....
And if you are using Ha double stack(bandwidth 0.5A) then the view is fantastic. Lots of prominence invisible in Ha single stack will show up in double stack and minor flare will appear as well illuminated cracks on the sun.
Actually l view that huge prominence in Ha double stack.....just beautiful and the biggest l saw in this cycle.

Today at 12noon to 12:10.....
At the edge where 3664 and 3668 are heading another big prominence.,now the shape of a fat U shape. The bottom of the inverted U landed on the sun surface approx 250,000 km apart. The max height is half that.
Thats the sun l like to observe.....but one thing....in single stack.....0.7A bandwidth, you may not be able to see it as l have to tune my echelon to see it.
Anyway try because it rare.
Happy observing!
Yes l used a double stack....0.5A bandwidth Ha scope.
