12th April. SE Australia. The sun appears to be fairly quiet at the moment. I managed 3 images of sunspots taken 48 hours apart - from 8th April to 12th April. All single exposures taken with a Canon 550d attached to a WO 81 mm refractor, Herschel wedge at 540 nm. AR 3634 appears to be developing. I...

2 April 2024. Sunspot number report for March. Another month (march) has passed and we begin a new month. So its time to report on the mean sunspot number for March. March's number came in at 104.9 which is below that of February's 124.7. The most prominent sunspot group for March was AR3615 which p...

30th March (SE Australia) I managed to get a final image of AR3615 this morning before it disappears from view on the western limb of the sun. To compare, I have also attached an image from two days ago. This has been an interesting AR to follow. Both images are single exposures with a Canon 550d, W...

29th March 21.31 hrs UT I noticed this image this morning recorded by the GOES-16 satellite. A spectacular release of plasma from the Sun's SE sector. It does not appear in any Ha images on GONG ??? I haven't yet found any info on it ?? Anyone know any info on it. Update: I have added another GOES 1...

A nice set of images of this AR. I like the second last image best.

Its been interesting to follow the evolution of AR3615 - maybe it will return?

26th March. SE Australia. A nice sunny day with good sky conditions. The large active region AR3615 continues to evolve into a nice cluster as it moves across the sun towards the western limb. The first image at 540 nm shows its position today together with the other sunspot regions. The second imag...

24th March. Shown are 3 images of the sunspots at 540 nm taken on 20th, 22nd and 24th March to show the changes that have taken place. The most prominent sunspot group at the moment is AR3615. The last image shows this AR in the Ha wavelength 656 nm. All are single exposures with a Canon 550d camera...

2nd March. Its the start of March so time for an update on the progress of Solar cycle 25. February saw a slight increase in the mean sunspot number from 123.0 for January to 124.7 for February. Two graphs are shown - the first from the Australian SWS, and the second from the USA / SWPC. Both use a ...
