What wavelength is that example image? 19.5 nm? That information would be useful to provide. In what wavelengths a coronal hole becomes apparent? --134.76.54.136 (talk) 08:46, 2 May 2012 (UTC)
A Novice's questions edit
Are coronal holes permanent? How long do they last? Do the frequency of them give new information as to the lifespan of our sun, and its eventual burn-out however many milleniums from now? Do the coronal holes have any relation to solar flares? ....Are these coronal holes something we need to be worried about? Marc S. Dania fl 206.192.35.125 (talk) 18:40, 30 July 2013 (UTC)
- permanent? No. They last a few weeks.
- Frequency. No idea. Probably not. Millions of years anyway,
- No direct relation to solar flares but they are the site of Coronal Mass Ejections, and hence Aurorae.
- Don't worry. Matt Whyndham (talk) 21:22, 11 November 2015 (UTC)
