The southern edge of the aurora should be visible in the middle USA-- Above the Winter Weather
The arrival of the shock from the last solar flare was 12 hours behind our
estimate, so the high auroral activity is occurring over Russia right now (8pm GMT) It will probably continue for another 12 hours so we expect high auroral activity tonight, Jan 21. The southern edge of the aurora should be visible from England, Northern Europe, and middle USA. Dr. Charles Deehr, Prof. Emer. Phys.

Dr. Charles Deehr wrote in an earlier notice: This means that there could be significant auroral activity in all areas on the night of the 20th/21st local time. This could extend for 2 more days. See the movie at http://gse.gi.alaska.edu/recent/javascript_movie.html Thank you for posting the link to the solar wind forecast simulation. Having read the underlying paper at the website, I am not following what the forecast simulation represents and whether it might be used by amateur observers to predict likely arrival times for CMEs. If you have some time in the future, you would consider posting a brief explanation of the display? http://gse.gi.alaska.edu/recent/javascript_movie.html - Thanks for your and Sam's continuing aurora notices. Many of us here do go outside and look. - Canopus56 |
