Dean Pesnell, Solar Dynamics Observatory – What happens when I click “this”?


On all the pages, for some reason, the link to your name and Kevin Addison on pages loops back to the page itself, not to email.

But I selected AIA 0171 for 2023-07-07 00:00:00 to 2023-07-07 23:59″59 at 4096 resolution and clicked.  As soon as I did I realized that was a mistake, but even now not sure how bad.

I cannot remember the cadence for the 4096 images. I do not know if it is trying to create an archive in FITS or some other format.  I do not know how many images that might be.  I do know how large the archive might be, if it is trying to put the whole day into one archive file.

My suggestion would be to have it TELL me, what I just proposed to do and ask me if that was what I intended.

I WOULD like to have some FITS 4096 images to work with.  I have been looking at, downloading and studying these datasets for several years.

“This could take a few minutes. Do not refresh this page” could well be much longer than a few minutes and generate something I cannot easily process.

There is no “STOP” or “CANCEL” or “PAUSE and CHANGE”  button.  No estimate of time to process, size or time to download.

23 Jul 2023 was the 25th Anniversary of the Internet Foundation. I have tried to set policies for the Internet to encourage open sharing of all human knowledge in forms that every human, every country, every age can use.  It is not impossible.  Staging large datasets is not hard.  You add a  summary of what it going to happen, and ask “Is this what you plan to do?”

There is no obvious entry on the left side panel “size of data, how to download, how to use”.  I will leave this running and in a separate window search to remind myself the cadence, size and processing of he images. The jpeg images are all LOSSY.  The pixels do not match the raw data.  With some of the FITS 4096 and corresponding jpeg 4096 and some of the 1024 movies, I can be more specific.

Thank you for these wonderful images, but I would like to suggest ways to make the lossless data more accessible. There a about 1 in a 1000 of students in the work who can work with this kind of data. That is several million.  Even if it were only a few 10 thousands, it would be worth doing.  Most countries are looking at the stars and planets, but the most visible is the sun, especially the vivid and complex image you provide, except they need to be lossless and easy to use from the browser, the only universal access on the Internet now.

Thank you for your time and attention.
