2 significant spot groups currently visible

[davenn]

hi gang

there are currently 2 significant spot groups visible traversing the face of the solar disk

The centre-left string is active region 2671 and the region near the right edge ( eastern limb) is
active region 2672. AR2672 will continue to rotate across the disk across the next 2 weeks.

800mm, f9, 200th sec, ISO200 and solar filter

Cool picture.
Both groups have a good chance for C-class flares.

Was this picture taken morning hours? (to make sure I understand the orientation properly) Or pm hours and reverse image?

West limb left side, east limb right side, not 100% certain if north pole is up or down ... I suspect it's up

this is visual view, non-telescope view as seen on spaceweather.com, sdac etc sites where E and W (and maybe N and S - not sure) are inverted
Tho I'm lead to believe that N and S poles are correct ( I haven't figured out how they invert E and W without doing the same to N and S poles ??)D

Ok thanks Dave, that helps.
If it's visual view it must have been taken am hours, because that's how I see the sun in the morning. (In the afternoon and forth, if we do the "rotation" over our head, it turns upside down. [BTW, your being in the South Hemisphere I don't think it matters other than having the Sun to your left (instead of right) when you look East, this time of the year ... (simple Geometry).] )

I have a photo taken near the end of the eclipse Monday 8-21-2017 from Oregon. The photo above looks to be near midday. It is rotated 180 degrees. Both the E/W and N/S are swapped. This is the view as would be seen in an astronomical telescope. If you add a diagonal you get the N/S corrected but the E/W is still reversed. I will add a photo if I can figure out how.

It depends on the time.

Please do! You have to create media first, I think.

The camera was tilted down on left a little to show more of the width of the sun. 11:33:01 PDT Aug 21, 2017. 2286mm (90 inches), f15, 100th sec, ISO 200 solar filter. Even though this is a 6" refractor it works just like a standard camera lens.

That's what I see pm hours. Is your image inverted for some reason?

I am in the northern hemisphere at about 44.5 degrees north latitude. On checking an image that I took with the camera level I would say that the photo that I posted is rotated clockwise approximately 46 degrees. Otherwise it is exactly as was seen with the naked eye.

Is the small spot to the left, next to the moon, group region 2672? If yes (which I assume) then the orientation for am hours is that of a telescope view (unless your instruments are not upright; 46 degrees would still project similar view). In other words your image is almost inverted; I don't know why it is or how you managed it.

davenn's looks like am hours, visual view. That's what I also saw am hours back then (upright visual view image) ... etc.
[That's why I originally asked the 'hours' question.]
