I heard that Elon Musk was going to put high resolution lossless format cameras on all his satellites — pointing at all part of the heavens, to give all humans a live stream of their part of the night sky. Thanks, Elon, for giving back the night sky. Two billion kids say thanks. @X, Could

Richard Posted on Twitter (“X”): @zdhnarsil There are many Internet topics badly fragmented because groups do not think globally. Solar groups ought to give one seamless “sun”. https://helioviewer.org/ https://sdo.gsfc.nasa.gov/ AIs COULD provide global context, but AI dev groups, themselves, provide no stability. Richard Posted on Twitter (“X”): Experimental view of the Sun, from 02 to

Halo CME @halocme These supra-arcade downflows (SAD) (including tadpoles) tend to follow a very big eruption as we see them here. twitter.com/TrestanSimon/s… Quote Tweet Trestan Simon @TrestanSimon The eruption associated with today’s X-class solar flare was also associated with supra-arcade downflows, dark tadpole-shaped features that sometimes appear descending above flare arcades.

I want observing stations near the sun to monitor it closely and continuously. Sunlight so close, might as well gather some into “atomic fuel”. Richard Collins, The Internet Foundation Richard: The earth has a specific distance and velocity for “geosynchronous” satellites. What is the radius and velocity of a solar synchronous orbit for a satellite

Hi Athiray, I was just going to write you. I am reading about soft x-ray camera noise. “Performance characterization of UV science cameras developed for the Chromospheric Lyman-Alpha Spectro-Polarimeter” And now reading “Modeling charge transport in Swept Charge Devices for X-ray spectroscopy” I have been tracking the solar imaging groups for several years, and slowly

“Global MHD Simulations of the Time-Dependent Corona” at https://www.researchgate.net/publication/371786836_Global_MHD_Simulations_of_the_Time-Dependent_Corona Robert, I am reading “Global MHD Simulations of the Time-Dependent Corona” that you, Roberto Lionello, and Viacheslav Titov wrote. The links you have at the top “NASA Grant NNX14AH71G” and “Streamer Belt” go to a ResearchGate page that says projects are no longer supported. I managed

Subject: Exactly how are the 4096_211193171 images made from AIA 211 193 and 171? 48 hour movies Dean, I am looking at these blended images, and they are helpful But I would like to be sure I know exactly what goes into them and also be able to change the composition. https://sdo.gsfc.nasa.gov/data/ https://sdo.gsfc.nasa.gov/assets/img/browse/2023/06/28/20230628_045709_4096_211193171n.jpg I asked

There is no “login” Considering the difficulty entering things in the form is there a URL based access to the same

The sun’s diameter is about 109 times the diameter of the earth. This is a movie of today’s sun. Bottom right you can set the playback speed to 0.25 so you have time to look around. I use a magnifying glass in Windows to look closely. A lot happens. https://sdo.gsfc.nasa.gov/data/latest48.php?q=0171 These are snapshots of the

Dean, On all the pages, for some reason, the link to your name and Kevin Addison on SDO.GSFS.gov 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,
