Recommended Posts

Image 1 – Solar Disc

Image acquired at 09:51:07 UTC. Bo +1.26˚, Lo 95.34˚, P -8.84˚. There are nine active regions visible on the solar disc this morning, including a number of filaments. There is an especially long ‘reverse-s’ shaped filament positioned through active regions 13030 and 13032. Some nice prominences appear on the limbs particularly the eastern side which has several small breakaway areas.


Image 2 – AR13031 & AR13037

AR13031 (S25W44)

Currently comprised of 15 sunspots and classified ESI, this region occupies 420 million square kilometres of the chromosphere. It has diminished in size in the last 24 hours and the sunspot count has also reduced by 5. AR13031 has been producing flares, its largest eruption so far being an M1.6 class flare the previous day.

AR13037 (S21W55)

Now approaching the western limb, AR13037 continues to increase its sunspot count from 8 to 13 in the last 24 hours. Whilst smaller in the amount of real estate it occupies on the solar disc compared to its neighbour, it has grown in size and now covers c180 million square kilometres. Designated CSI, this region today produced a short burst C3.3 flare between 18:18 and 18:32 UTC. 


Image 3 & 4 – AR13033, 13034 & 13038

AR13033 (N18E01)

A relatively small region compared to the other active regions in this image, AR13033 is classified CRO. Overnight it has diminished in size and sunspots, with now only 6 spots visible. It has only produced two C class flares worthy of note the last being on 14 June 2022.

AR13034 (N01E12)

Located bottom centre of this image, you can clearly see that this is comprised of a single sunspot classified CSO. Whilst it has diminished in size since it first appeared on the solar disc, its sunspot count as remained stable at this level over the past two days. It has yet to produce any flares worthy of note.

AR13038 (N12E40)

Now rotated off the eastern limb, this region has grown in size from 30 to 180 million square kilometres and more than doubled its sunspot count from 3 to 7. Classified DRO this region has yet to produce any flares worthy of note.

Inverting this image reveals an interesting formation where separation has occurred from the main prominence on the eastern limb.


Image 5 – AR13033, AR13032 & AR13030

AR13030 (N19W31)

Classified DAI since 15th June, this region has increased its sunspot count from 13 to 17 in the last 24 hours but diminished in size by 120 million square kilometres to 240 million square kilometres. It is actively producing flares with a C4.3 eruption taking place today between 14:55 and 18:18 UTC.

AR13032 (N21W21)

Finally, we have AR13032. This region has remained consistent in size over the last 24 hours at 210 million square kilometres but has lost a single sunspot taking todays count to two. AR13032 classification has changed from HSX to CSO and it has produced four flares worthy of note, three have been C class and one, an M3.4 class flare, erupted on 13 June 2022.
