Another great image of our Sun taken by member Jim Burchell on the 21st March 2025. Underneath is an image Jim took on the 16th March 2025; you can see how the sunspots have moved across the Sun since the 16th.
Both images were taken with an Pentax KP body attached to 102mm F11 Altair Astro refractor fitted with a solar filter and then coloured in Snapseed.

Two superb images of the Sun today taken by member Jim Burchell. As you can see the Sun is very active with lots of sunspots.
Jim's 1st image below, a single shot; was taken using a 102 MM refactor with a Pentax KP body attached set at F11, 320 sec and iso 100 plus a solar filter.
Jim's 2nd image, which is just a single shot; was taken using a SeeStar S50 smartscope.
Below is an image taken from Spaceweather.com showing all the sunspots with their labels. As you can see there are lots!!!!!

A super image of our Sun taken by member Jim Burchell on the morning of the 4th October 2024. As you can see the Sun was very active with many sunspots including sunspot AR3842. The 2nd photo has the sunspots labelled.
Jim wrote ''The images show Sunspot AR3842 which released two X-class solar flares (X7.1 and X9.1) and a series of M-class flares.''
This means Sunspot AR3842 has produced the strongest solar flare of Solar Cycle 25 so far. NASA's Solar Dynamics Observatory recorded the X9.1-category blast.
Jim acquired his image using a Pentax KP body attached to a 102 mm F11 refactor; 1/320 sec; iso 100 and a Baader Astrosolar Safety film was used.

A fantastic white light image of the Sun taken by member Jim Burchell on the 23rd August 2024 from Dartford. As you can see the Sun was very active with lots of huge sunspots. Jim took the single shot image using a white light Baader planetarium Astro Solar Filter and a Pentax KP body attached to 102mm F11 Altair Astro refractor at 1/320 sec and iso 100. Then processed in Snapseed.
Below is a spaceweather.com photo of the Sun with the sunspots given their number taken on the same day.
