Full disk 16-06-2020
Hi,
Sunny as usual and here today's Blank Sun disk except of some filaments and a filaprom near the disappeared AR 2765 area.
Hopefully the bright spot seen in the Heliographic image of today appears tomorrow at the Northeastern limb at about +20°

Hi Rainer,
The filaprom looks great on the solar disk. I have always wanted to ask you, what are those slightly darker lanes on the first image? Are they caused by clouds?

Re: Full disk 16-06-2020
Very nice images Rainer. Clouds here have prevented me from getting a decent view. That filaprom looks great! It looks like we have a blank WL sun again. Minimum isn't over yet.

Re: Full disk 16-06-2020
Hi Alfred,
That is the difference between the Hot Spot area and the corners. BTW my H-alpha disks are always a mosaic of 9 images. That is why they have this pattern. Do you look at my images at full size ? Open the image in a new tab and when the mouse shows a loupe with a plus sign click on the image. My Sun disks are approximately 1870 pixels in diameter.what are those slightly darker lanes on the first image ?
While the darker areas oscillate around 190 the brighter areas oscillate around 210. So there is a color value difference of about 20. This measured in 8 bit colour depth. Perhaps it could be killed using a flat but that is too much work for me. I am lazy by nature
Looking at it as an Icon the dark lanes are more visible then at 100% size.

Thanks Rainer for the explanation. Yes, flats should resolve that. They are lovely in full resolution too!!
