tniickck Posted July 6 Share Posted July 6 looks like we have a new fairly large region with close opposite polarity zones. hopefully, it builds more complexity Link to comment Share on other sites More sharing options...
Popular Post Jesterface23 Posted July 6 Popular Post Share Posted July 6 (edited) We'll still need to wait a few days to see what the magnetic structure is like from SDO as the region is too close to the limb. The big spot umbra could be a strong positive polarity spot. .................. *Strong negative polarity spot. I'm never going to remember the color table right lol Edited July 6 by Jesterface23 7 Link to comment Share on other sites More sharing options...
Sam Warfel Posted July 6 Share Posted July 6 So far it's looking large but non-complex. I'm also not seeing much in the way of flaring from it. Fingers crossed it develops some complexity for us. 1 Link to comment Share on other sites More sharing options...

Here's a gif: I wonder if that weaker area in the middle in the m-gram is an artifact or whether there's actually something about the spot that's causing it to look like that. I also wonder what the positive area really looks like, if it's really just all penumbra or if we'll start seeing some smaller spots as it rotates. Certainly peculiar. Looking at the PFSS of the m-gram it looks like a significant part of the field is connected to the positive area near 3366 and the surrounding cluster: 4 Link to comment Share on other sites More sharing options...

Definitely waiting for it to rotate further to see what the positive polarity area looks like. At this point it is pretty clear the issued pixels aren't an artifact with them being almost centered in the umbra. This is at least the 4th occurrence of the cycle that I've noticed, but none of them compares to this one. 1 Link to comment Share on other sites More sharing options...

Are you sure this is correct? I thought that the outward and north polarity were associated with red and yellow.

Yeah, that's what I was thinking too, because it doesn't look quite like those artifacts I've seen previously at least, which look more..."glitchy"; but it could be something similar, not really sure. Will be interesting to see it closer to the center for sure. 2 hours ago, Patrick P.A. Geryl said: Multiple small spots are now forming. Do you think they're really forming, or just starting to appear properly as we get a better view? I would think it's the latter, but I'd certainly be happy if it's developing too. 1 hour ago, Calder said: Now I’m confused. Are you sure this is correct?

This is also why the north pole of a magnet points north here on Earth, as the magnetic pole located near the geographic north pole is actually the south magnetic pole. As for the region, I'm not quire sure. It doesn't quite look like the artifacts I've seen earlier, as Jesterface says too, so could be something else, like a weird configuration. But it does look weird, it wouldn't surprise me if it's still an artifact of some sort either. Edit: Actually, now I see what seems more like that type of artifact: Certainly seems plausible that it's just due to the field strength, that spot is pretty massive.

If you have decent vision you can indeed see 3363 pretty well with eclipse glasses. I couldn't make out the shape of it of it but could definitely see the dot. Now, something about my observation brings up another question though. From my vantage point, the dot on the sun was on the right side of the visible disk whereas the HMI magnetogram image puts it on the left side. Is this a difference in perspective due to the SDO's position in space? Is it a mirror image or was I maybe seeing the wrong spot? Doesn't look like there's anything I could have mistaken 3363 for. It's also the only spot I was able to see. 1 Link to comment Share on other sites More sharing options...

If it is the spot you saw, it should be about 1/2 way from the center of the Sun to the edge of the disk either way with where it is right now. 1 Link to comment Share on other sites More sharing options...

I didn't even think about my orientation in relation to the Earth's and Sun's poles. Kind of embarrassing really for someone who owns an telescope with an equatorial mount. 🥴 Link to comment Share on other sites More sharing options...

Promising position for sure, and aesthetically pleasing to boot. At a first glance it looks like the filament is being flung more southward, but I'd guess it could still cause some ejecta to head our way once it releases. Eagerly awaiting coronagrams for this one. 1 Link to comment Share on other sites More sharing options...

MinYoongi Posted July 11 Share Posted July 11 looks southward to me? south-west? btw, is this a bug/glithc or is there blue in the hole in the red? looking at the SDO movie, i can see such a blue part in the hole at 6:30UTC already, then disappearing so maybe glitch?

From the previous discussions I think the consensus was that it's a glitch due to the strength of the negative polarity in this spot being greater in that area than the software is calibrated to translate.

Ah ok. i thought it may be positive (blue) growing in the red. so thats not real likely? i posted the pics with timestamps, it looks like a slight blue rim was already there in the utc day morning. to the cme: A friend on twitter and i are speculating, he says its a broad sweep and could be earth directed. i say its too much south/west. what do you say? @mozy @Philalethes Link to comment Share on other sites More sharing options...
