April 2 2024. Ha Observations.

Post by DeepSolar64 »

My session time was from 13:30 until 14:00 UTC. The skies were partly cloudy to mostly cloudy. The temperature was a warm 69F ( 20.5C ). The seeing looks to be a bit below average.

Coronado SolarMax II 60 SS. 16x and 25x. ( 656.28nm )
I can see eight plages in the chromosphere today. Seven in the northern hemisphere with two labeled and only one in the southern hemisphere. It is unlabeled.

I can see five plages in the NE quadrant. Four of these form a sideways cross shape. AR13624 marks the top of the cross. What a fitting symbol for the Easter season! The northernmost of these plages, the left side of the cross, was quite bright. I checked for flares but none were in progress. I could see two plages in the NW quadrant. KSO shows one to be AR13626 but I am not sure which one it is. An easy filament is seen near the NW limb.

Three easy filaments looking like tattered lint or cloth fragments lie in the SW quadrant. I see no plages there. I can see some scattered plaginess in the SE quadrant and there are also some filaments there too.

Single Stack shows all the proms shown on the limb that can be seen in the GONG images. One on the western limb just below the equator is especially noteworthy. I could see some small changes in it during the half-hour of observing. A projection reaches south from it and later in the session a thin spike came up under the southern end. It showed up on the GONG CTIO image too!

The usual mottling of the chromosphere is visible.


Carpe Lumen!

James

P.S. I did not see the faint floating plasma above the NW limb on the GONG images. The SMII90 in SS probably would have revealed it.

Half an hour well spent James. We had t-shirt weather here this afternoon, it was nice when the sun came out. Away from home stopping with friends at the moment, but back home on wednesday, so hopefully the sun will come out for a bit!

Alexandra,
You are very welcome! I hope you had a wonderful Easter.

Stu,
Thanks and you are very welcome.

Mark,
It was a half hour well spent even if I did have to wrestle with clouds. Good luck on tomorrow's session.

James
