Title: Current condition of Sol
Post by: R.R. Book on December 07, 2019, 01:45:22 PM
Vice published a story a few days ago about what NASA's Parker Probe recently discovered about the sun: that its current wind speeds exceed any previous models of what was believed to be possible for the sun:

Scientists say the unexplained rogue waves and high winds mean we are “missing something really fundamental in our standard models of the Sun.”

However, the story also featured a startling SDO image of our sun gone dark, which would seem to be the greater story, though nothing was said about it:

Dr. Claudia Albers has recently published papers announcing that our sun has gone dark, but this was the first time that I'd seen an actual photo of it.

Could that image be for some particular narrow wavelength band that sees flares only?
The article does not provide source reference.  (Unprofessional journalism.  Common problem.   Uneducated author or deliberate disinfo?)

Vice is a joint Canadian and American techie alternative news outlet that has been around for a quarter century.  Here's the link provided by the article for the sources referenced in Nature journal, which is 150 years old this year (est. 1869):

https://www.nature.com/articles/d41586-019-03665-3

The author, Becky Ferreira, is a science and tech reporter who has been contributing to Vice since 2013.  As an old English and journalism teacher myself (until I went to grad school for a career in social work), I feel that her articles are well-written, though brief, and appear to faithfully link appropriate science journals and technical news media.

Will reiterate that the story in Vice was not about the sun going dark.  It was the incidental SDO photo that captured my attention.  NASA sometimes posts visuals and then later removes them, but I agree that we might have benefited from a photo link.

It would seem difficult to justify referring to a mere photo as "disinfo" posted by an "uneducated" author, who writes in a coherent manner, compared with much of what clumsily passes for journalism these days. 

Can you explain more about special photography that can make the sun appear dark?  That might be educational for all of us, as I'm not aware of it.

This is the credit for the image that is given in the article.
"The Sun. Image: NASA/SDO"
It is not a link, however, so I cannot read/check it for myself.  Not pro level tech reporting.

Why include an image that is irrelevant to the topic of the article?   Not pro level tech reporting.

Some telescopes, both land-based and in space, detect radiation in wavelength bands that are outside of human visual detection.  E.g, ultraviolet, gamma, radio, infrared, X-ray, etc.

Ref. "It takes more than one kind of telescope to see the light" at https://science.nasa.gov/science-news/science-at-nasa/1999/features/ast20apr99_1

Here is a snip from "SOHO solar and heliospheric observatory"   at https://sohowww.nascom.nasa.gov/gallery/Movies/flares.html  that shows a green Sun except for bright flares.

Somewhere in the Internet you can view images of the Sun in wavelengths selected from a menu.  "Suspicious Observers" does that sometimes.

What specific type of light / telescope would you say photographed that image Jim?  Are there similar images that you can show us, as examples?

Here is an image similar to the one in question.

From http://solar.physics.montana.edu/YPOP/Spotlight/Today/xray.html

The Sun has been relatively quiet recently, if I remember commentary correctly. so I am guessing that there was a moment when only a few flares were emitting X-rays, and that produced the image in question.

Jim, I'm posting to the admins board to begin a conversation about some in-house issues that this thread has brought up.

Jim, yes, please join in on the discussion there, which R.R. mentioned.
Unfortunately I will be gone off the board for a few hours but please read what is posted there and sorry for personal family and health reasons today, have not even been able to really read and sort out this topic.
Wishing You all the Best,
Barb Townsend
