Solar storm preparedness and mitigation

[Astroplane @AstroplaneHQ]

From an astrophysics perspective, “Space Katrina” is the only thing any of us should be working on.

[Space Weather Watch @spacewxwatch]

No new NASA/Solar Dynamics Observatory data will be available for an extended period of time as the server room in the Joint Science Operations Center at Stanford University is currently flooded.
Here are the last pictures taken of the Sun. Hopefully it doesn't go nuts now...

G4 Severe Geomagnetic Storm Alert issued without a G4 Watch or G4 Warning! This means not only is FEMA now issuing orders to federal agencies, it means there was no forecast of G4 assumingly.

A large solar filament stretching more than 350,000 km is currently located across the southeast quadrant. For now it remains magnetically anchored in place, however should it become unstable and collapse, a CME would be very possible. https://t.co/aqK4Q6XLqw

Woah, Mexico. A technical reminder of what this means (@xkcd). Didn't quite make the middle band.

[National Weather Service @NWS]

ICYMI, @NWSSWPC has issued the first G4 (Severe) geomagnetic watch since 2005. The aurora tomorrow may become visible over much of the northern half of the country, and maybe as far south as Alabama to northern California.

Will the ☀️ provide this payload with some fireworks? Amazing engineering.

An ultra close-up shot of sunspot region 3664 this morning with my 16" scope under great conditions.
This region is so big it's visible to the unaided eye (with eclipse glasses of course!)

You should always be prepared for severe weather. Follow updates from your local officials. Download the FEMA App to receive real-time @NWS alerts, safety tips, & sheltering information for up to 5 locations:

SWPC has issued a G4 Watch, which triggers elevated threat planning by FEMA. The giant sunspot cluster is visible with eclipse glasses alone and "cannibal CMEs" may occur!

It's a #solarstorm train! We now have FIVE storms headed towards Earth! Storm 2, 3, and 5 will be direct hits as seen in the coronagraph imagery. Impacts start around midday May 10 and will continue through late May 12 at least. G3-level conditions & extended #aurora possible.

[NOAA Space Weather Prediction Center @NWSSWPC]

WATCH: Geomagnetic Storm Category G4 or Greater Predicted
Highest Storm Level Predicted by Day:
May 10: G1 (Minor) May 11: G4 (Severe) May 12: G2 (Moderate)
Issue Time: 2024 May 09 1722 UTC

Awesome to be on NPR's Cool Science Radio! It is urgent that space and climate scientists start to seriously consider the impacts of burning truck-size satellites in the atmosphere 24/7.

@James_Canno @natashaloder @philipcball Boley’s work already shows potential ozone depletion from the alumina, this is just looking at one level higher. The satellites are mostly aluminium & they turn into plasma dust that stays there indefinitely. The charge of the ionosphere is going up bc of this according to CCMC

[Astroplane @AstroplaneHQ]

@natashaloder @philipcball @James_Canno Meteors are only 1% conductive material, as cited by Boley’s work. One satellite re-entry is *3x more conductive material* than the 50 tons of meteors per day. The results mean humanity is impacting space above the atmosphere & this could increase ionization of the lower levels

[Astroplane @AstroplaneHQ]

Governments are very aware of the problem but will not warn you or prepare you for extreme space weather. Why not? Well, if everyone wanted to live in an off-grid Earthship & have their own food garden, the economy would suffer. But there is this resource: https://t.co/2gbyBSjdcZ

[Astroplane @AstroplaneHQ]

Thank you @StartsWithABang for having me! 2 topics I forgot to discuss: surface mass ejections (could our Sun eject a mass *billions* of times greater than a CME?) & climate/space weather.

Anyway, I urge all to ask, “What would I do if the power went out & never came back on?”

Starts With A Bang podcast #89 – The active threat of the Sun

Thanks to plasma physicist Sierra Solter for being a fantastic guest, and discussing with us how the Sun, giver of life, can also cause human civilization to crumble in a flash.

It will be interesting to see whether last night's short-lived G2-level #solarstorm will help bring down those six #Starlink satellites that failed orbit-raising due to the last G2 storm back on September 5. This is just another reason why #SpaceWeather can no longer be ignored.

MONSTER SUNSPOTS COMING OVER SOUTHEAST LIMB: Not sure if it is one group or two, more info in a day or two. Sorry no reports today (perhaps later?) - been watching QEII funeral since early this morning - highly emotional. Need to get some sleep right now. :)
