Evolution of AR12829

[Hughsie]

This last week the weather has me kicking my heels so I decided to have a look through some recent data and was surprised to see that I had eight consecutive days of solar imaging at the start of June. Not only that, AR12829 featured in most of the captures so I wanted to share this little montage showing its evolution.

 

Images 1 & 2  - 3 June 2021 - AR12829 makes an appearance on the eastern limb. Just a single spot on show. Classification HRX - a unipolar sunspot.

        

 

Image 3 - 4 June 2021 - A close up using a 5x Powermate. A bit of a noisy picture but nice to catch a flare building up. Classification CRO - an open bi-polar sunspot group with one spot having a pnumbra. Possibly 4 or maybe 5 spots on show.

 

Images 4 & 5 - 5 June 2021 - AR12829 ‘inverted’ to bring out the detail of the filament to its lower left. Classification now CAO. Still an open grouping.

        

 

Images 6 & 7 - 6 June 2021. At 06.43 we have a classification of CRO - still a bi-polar grouping with a rudimentary penumbra around the largest spot (left side of disc). A close up using a 3x Barlow is shown in image 7.

       

 

Image 8 - 7 June 2021. Still classified as CRO, however, the eastern spot is more developed.

 

 

Image 9 - 8 June 2021 - Classification has changed to DSO, a bi-polar sun spot group with a penumbra at both ends (not clearly visible here) also the region looks more symmetrical about the vertical.

 

 

Image 10 - 9 June 2021. A rush of blood to the head and armed with a Grade C in CSE Art I decided to throw a tin of paint at the poor thing. Still classified as DSO.

 

 

Image 11 - 10 June 2021. AR12829 shows little difference to the previous day, still classified as DSO.

 

Enjoy your day.
