What is this large, slowly developing bright blob in the northeast of LASCO coronagraph?  It's slightly farsided now, but the source should be visible soon.  It is drawn into the current SWPC synoptic map.  Is it flux? plasma? filament? solar wind?

It looks like a few small CMEs launched from the northwest region that came into view. Then there looks to be a larger filament eruption in progress over the limb not in coronagraph imagery yet.

.....

Actually it looks like a filament was disturbed, so that is actually another region over the limb.

I find it odd that these ARs are such a relatively high latitude, with the solar cycle reasonably well advanced now I would have thought we’d see more lower latitude spots 

I think this might just be an optical illusion based on the fact that we see Sol's axial tilt head-on in early March (which we're only ~2 weeks away from) and early September (not related to the equinoctes, as this would essentially be the solstices of Sol if it and Earth were to exchange roles as luminary and luminee); this means that what appears to be the equator of the visible disc at the null meridian is actually ~7 degrees south, and due to this and the depth distortion of the flat projection many regions in the northern hemisphere will seem to be at more extreme latitudes than they really are with respect to Sol's actual equator. If you look at e.g. SolarSoft, you can see how the actual equator bends upward due to this effect:

In reality 3229 isn't that far north, it's situated at ~25 degrees north (with most recent flares located to 24N), which sounds reasonable to me for the current part of the cycle, given how the spots start around ~55 degrees (as Scott likes to remind everyone). 3226 recently flared as close to the equator as 07N, and most notable regions seem to be somewhere around 10-25 degrees from the equator.

I was wondering is this might be true  as well. tnx PB!

If the upper region is what was 3234 last rotation, it should become visible tomorrow at some point.

It looks like the southern spot is in same zone as AR3230 from last rotation (C10). On last rotation it was fairly quiet, with a maximum flare of C8.6. Given that it survived transition of farside let's hope it can do better this time !

Something pretty large just erupted from a benign looking region on the south east.  Looks like a pretty decent filament eruption. Anyone know if there’s  anything more to this?

Not that impressive looking, it mostly all fell back onto the surface.

Also does not appear to be connected to any incoming regions.

Hey there, I’m a little confused. The NOAA forecast claims that a CME did come from a prominence eruption in the southeast and that it could potentially be earth directed

Also Keith Strong is claiming a huge CME came from the prominence. Granted, his takes are mixed to say the least but just wanted to hear your thoughts

While the filament itself was big, only a part of it snapped and the eruption wasn't that impressive, a lot of the plasma fell back. It could have been huge though if it really let loose.

Also I unfollowed Keith on Twitter few months ago, not a fan of his wording for everything, extreme exaggeration most of the time.
