January 20 2023 Observations. BIG spot of AR13190!!

Post by DeepSolar64 »

My session time was from 16:10 until 17:00 UTC. The skies have some high cloudiness but the seeing is above average. The temperature is 47F ( 8.3C ) Breezy.

Orion 70mm Solar Telescope. 25x, 41.5x, 50x, 62.5x and 100x. ( WLC )
I can see a whopping eleven active regions on the white light photosphere today! Eight labeled active regions are counted in the northern hemisphere ( SWL ). Three are labeled in the southern hemisphere counting the impressive AR13190.

AR13199 is seen as a small grouping of spots in the far NE near the limb. I see five spots there with another just to the south. Faculae can be seen with this system. NW of AR13199 lies AR13198 with a structured spot and some pores. SW of it lies AR13197 and AR13196 with both showing as groups of sparsely scattered small spots and pores. AR13192 in the NW quadrant shows itself as an easy scattered group of spots and pores. Several of these show umbra-penumbra form. AR13191 just to the SW of AR13192 is made up of two spots. The westernmost of these shows better form with a double umbra surrounded by a shared penumbra. I see AR13195 to the north of AR13191. I see it only as a single large pore. AR13186 near the NW limb shows a well formed structured spot tilted at a sharp angle. To it's NE is what appears to be a tight grouping of tiny pores. Faculae are easily seen here.

AR13184 is seen as two close together spots amidst faculae nearing the SW limb. Well SE of AR13184 lies AR13194. I see it as a smattering of four spots/pores. AR13190 is truly spectacular today. The umbra looks like an embryo of sorts with a spike on the top of an eastward facing tail. Two light bridges can be seen crossing the tail at 100x with one being easier to see than the other. Another light bridge is seen at the SW end of the umbra looking like a downward facing mouth! A " fin " is seen at the back hump of the umbra! The penumbra is mottled with an irregular edge. Lighter gaps are seen in the NE and SE parts of the penumbra. Smaller spots and pores are easily seen ESE of the big spot. Another pore is seen just NW of the big spot. I can visually see more than 90 percent of the details shown in the SDO HMI continuum 4K image but with a bit less contrast and the SDO shows the individual granules which are not seen in the Orion70 though I can easily see the overall fine granulation of the disc. I see no active regions in the SE quadrant though I can make out some faint faculae near the SE limb.


Coronado SolarMax II 60 DS. 16x, 25x, 33x and 50x ( 656.28nm )
Like continuum I can see eleven active regions on the Sun. This time in the chromosphere and in Ha. As in continuum all active regions carry NOAA number labels.

AR13199 near the NE limb shows itself as a plage. Three plages in a line are located NW to west of AR13199. They are AR13198-97-96. A filament is seen on the northern edge of AR13196 and I can see the spot of AR13198. AR13191-92 is seen as a large complex of plage lying now in the NW quadrant. It's quite big. I can see three spots in AR13192 and two in AR13191. I can also see a long thin filament in AR13192 and a curved filament in AR13191. Another thin filament is seen just east of AR13192. NW of the complex and NE of AR13195 lies a larger easier filament. AR13186 near the NW limb is seen as fainter plage with a spot. AR13195 appears as just plage.

AR13184 near the SW limb shows itself only as plage. Well SE of AR13184 lies the plage of AR13194. It's appears as a streaming of plage nearly attached to nearby AR13190. AR13190 now west of the CLM in the SW quadrant shows itself well. I can easily see the spot including the umbra and penumbra and can see the spot's umbral eastward pointing tail. A fine filament lies NE of the spot. Plage lies east of the spot. I can also see the effect of the system's magnetic field on the surrounding chromosphere. The only things I can see in the SE quadrant are a couple of filaments.

I can see the small prominences shown on the GONG El Teide Ha images visually but I did not concentrate on them.

The mottles are easily seen across the solar disc.


WooHoo!! It's FRIDAY!! :hamster:

James


P.S. I notice a discrepancy in the numbering of the active region SW of AR13190. SpaceWeatherLive has it as AR13194 while SolarMonitor has it as AR13188. I don't know which one it actually is though I would guess the former. Anyway, you at least will know the active region I am referring to!

Hi James...

Great to read about your session, and the WL image is very good :bow

I'm back in cloud again, so I'll have to follow the sun form here ;)

Brian,
The observational report is mine and I wish I could lay claim to the white light closeup. It's a crop from a 4K SDO HMI continuum image. Visually I could see most of what the image shows.

It's clouding up here too. Rain is forecast to move in here tomorrow afternoon.

Hi James...

My bad, I didn't read the fine print on the image title ;)

Thanks and welcomes everyone and Brian that's ok. The image looks very natural. I wish I could do one this good. I have approached it a time or to but no cudos.

Thanks James, I notice that your 20th Jan images don't have that huge, fat filament like others are showing, did it not stay long?

That filament lifted off. I was hoping to catch it on the limb as a prominence but it lifted off before it got there. Warren posted a nice GONG animation of the liftoff.
