May 24, 2018: Sun in WL and Ca-K with three ARs (one brand new)

[michael.h.f.wilkinson]

Got some solar data early this morning, before going to work. I noticed a new AR with a lot of faculae, some pores, and a sunspot right on the edge of the disk. Difficult to spot, but it should get easier. One AR seems to be losing steam, however. It still shows brightly in Ca-K, but is clearly shrinking in WL. On the plus side, there are quite a few faint proms visible in the part inverted Ca-K image, so fingers crossed for more activity.

Best seen at full-res as usual.

Cheers guys. I just had the SolarMax-II 60mm out for a look in H-alpha, and was surprised to see I couldn't really spot the proms in the east. A bit odd.

That’s strange Michael. They are showing quite well here.

Nice set as always, Michael.

Your hint of a third AR may force me to get out the Lunt for a full disk.?

Thanks for sharing your work.

3 A/R's maybe the Solar minimum is already over........? A fine set of images there Michael, good to see some decent activity again.
