#StefanBurns excellent report on the epic events happening around us, & the #SolarEcclipse is only 1 part of it.
#GifsArtidote i am going out to #ThePark to watch from my favourite willow tree root seat & take a little picnic & my last beer, a guinness.
there's a higher hill with one dead tree where i'll have a clear view.https://www.youtube.com/live/z6GWFU9MiW4?

Geophysical Alert MessageSolar-terrestrial indices for 10 August follow.
Solar flux 95 and estimated planetary A-index 5.
The estimated planetary K-index at 1200 UTC on 11 August was 2.00.No space weather storms were observed for the past 24 hours.
Space weather for the next 24 hours is predicted to be minor.
Geomagnetic storms reaching the G1 level are likely.

Space Weather
In ancient Greece, a "meteor" referred to any natural phenomenon in the sky or atmosphere, including rain, rainbows, lightning, comets, and shooting stars.
As you probably know by now, tomorrow sees two meteorological events and a total solar eclipse. It'll be a long day for anyone keen to view all the events!
The annual Perseids meteor shower peaks in the hours before before sunrise (tonight) on the 12th. The radiant is circumpolar in the N hemisphere. As the moon is nearly "new", the dark sky should give good viewing where the sky is clear.
The full solar eclipse will be visible late in the day on a path starting at the North Pole, then cutting down across Greenland and the western tips of Iceland, down the Atlantic Ocean curving eastwards across the top of Spain and the western Mediterranean Sea. A partial eclipse will be seen at sunrise in N America, the UK & Ireland and most of western Europe, and West Africa as sunset approaches.
A couple of solar storms are incoming which could cause geomagnetic storming up to G1 levels on the 12th. This, combined with straggling Perseids meteors, should make for some fantastic photo opportunities.
As most people will be viewing the partial eclipse phase, remember DO NOT look directly at the sun without the correct solar glasses or a solar filter. I've already seen on Facebook people suggesting to use cheap welding goggles to view the sun! This is EXTREMELY DANGEROUS as most welding goggles are NOT dark enough to filter out harmful UV and IR solar radiation, and permanent eye damage could result.
Radio Propagation: HF radio conditions are currently poor due to the low solar flux. The minor geomagnetic storms tomorrow may further impact conditions at higher latitudes and cause minor GPS disruption.
The eclipse will have a temporary impact on the ionosphere as the moon's shadow reduces D-layer absorption.

Otherworldly #music albums feature #spaceweather data
Triggered by #solarwinds and lightning, these waves can tell scientists about space. Scientists at the British Antarctic Survey use them to study #space weather and its links to Earth’s climate.
The radio waves, when converted to sound, make “weird and wonderful noises” that have a melodic quality to them. That inspired him to team up with professional artists to transform the data into music.

Space Weather
Conditions are recovering following yesterday's "slow" geomagnetic storm.
What was unusual was that the solar wind speed was mostly between 350-400km/s during the storm. This had space weather scientists wondering if it was coming or not.
Aurora was seen down to higher mid-latitudes at the peak, which made it to around Kp6 overnight in Europe.

🔴 Sustained southward Bz detected
Bz has been consistently southward (currently -6.3 nT). Sustained southward fields maximise geomagnetic coupling and support aurora activity.

A moderate G2 geomagnetic storm is in progress. IMF Bz is -10nT. DST ring current is charging up at -55nT.
HF propagation will be severely affected at polar latitudes, and moderately affected at high latitudes.
GPS will also be degraded at mid-latitudes and above.
Aurora may be visible at upper mid- and high latitudes.

A G1 Geomagnetic Storm is in progress.
A strong substorm was just noted on a high-latitude magnetometer in Alaska just now.
Amateur radio operators at high latitudes are reporting contacts reflected from the auroral curtain.
Aurora has also been seen on a live webcam in Australia.
