One of the world's leading space science experts predicted a "direct hit" from a solar storm.
Dr. Tamitha Skov, known as the "Space Weather Woman," is a research scientist at the federally funded Aerospace Corporation and is an award-winning science educator on social media
On Saturday, she posted a NASA prediction model video.
"Direct Hit!" she predicted. "A snake-like filament launched as a big solar storm while in the Earth-strike zone."
"NASA predicts impact early July 19. Strong Aurora shows possible with this one, deep into mid-latitudes," she explained.
She said there could be disruption to GPS and amateur radio.

(11,780 posts)That wont be too bad. I suppose to make the prediction she has some idea of the intensity but historically a big solar storm and a direct hit could lead to much worse so maybe big is relative.

(52,389 posts)Some telegraph lines seem to have been able to produce a sufficient geomagnetically induced current from the electromagnetic field to allow for continued communication with the telegraph operator power supplies switched off.[25] The following conversation occurred between two operators of the American Telegraph Line between Boston and Portland, Maine, on the night of 2 September 1859 and reported in the Boston Traveler:
Portland operator: "Will do so. It is now disconnected."
Boston: "Mine is disconnected, and we are working with the auroral current. How do you receive my writing?"
Portland: "Better than with our batteries on. Current comes and goes gradually."
Boston: "My current is very strong at times, and we can work better without the batteries, as the aurora seems to neutralize and augment our batteries alternately, making current too strong at times for our relay magnets. Suppose we work without batteries while we are affected by this trouble."
Portland: "Very well. Shall I go ahead with business?"
Boston: "Yes. Go ahead."
The conversation was carried on for around two hours using no battery power at all and working solely with the current induced by the aurora, and it was said[by whom?] that this was the first time on record that more than a word or two was transmitted in such manner.[26]

But it has to be the big one at the right orientation for a direct hit. Which historically is only once a century or so.

(4,635 posts)I'd love to see a brilliant aurora again, though. Last time, late 80s maybe, the cars were stopping on the freeway shoulder to have a peek at the several mostly green swirls. Think the weather report is for 90s again, so likely too humid/cloudy w/pop up storms at night.

A: What has the German cognate mager as in ermagern, Alex?
Since you speak German, I thought I would throw in that last bit for fun. Checking on the verb ermagern (to make sure I was not making up a word) led me to few references to it online. Weirdly, one reference is from a book from (possibly) 1710, Der Curiöse Künstler, page 20, Num. XII., paragraph 1, line 2 - "wann er ermagert".

Were you familiar with that verb by chance? I must have run into it in one of Hesse's works or Goethe's works but don't know any longer. I'm just asking out of (ironically) curiosity.
Additionally and possibly interestingly, the publisher's "foreword" ( "Des Verlegers Bericht an den geneigten Leser" ) even mentions a "Lateinische Sprichwort": vino vendibili non opus.
