“The #WMM is officially released today, ensuring users can have the most up-to-date information so they can continue to navigate accurately for the next five years,” Dr #WilliamBrown, global #geomagnetic field modeler at #BGS (British Geological Survey), said in a statement.”

A new magnetic correction is in, valid to 2029.

Para aquellos interesados en la actividad solar y la tormenta solar que ocurrió la semana pasada, acá hay una comparación de su magnitud, con el evento de Carrington. Una medida que se suele utilizar para indicar la intensidad de estas tormentas geomagnéticas, es el Dst o Disturbance Storm Time, que es una medida de la intensidad de las corrientes de partículas cargadas que se generan entorno a la Tierra durante estas tormentas. Para que tengan una idea, este índice es 0 si no hay alteraciones, y se vuelve negativo ante la actividad solar. Suele tomar valores entre 0nT y -100nT y son contadas con los dedos de la mano, las veces que supuestamente ha superado los -150nT o -200nT. La tormenta que acaba de ocurrir superó los -400nT y el evento de Carrington de 1859 se piensa que rondó los valores de entre -1600 y -850 nT. Adjunto una breve referencia del libro Space Weather and Coronal Mass Ejections (2014) de Tim Howard y las capturas de los registros del mes de abril, donde se muestran los valores normales y lo que va del mes de mayo, donde se muestra el evento de la semana pasada. Ahora, tengo entendido que el daño en instalaciones eléctricas y lineas de alta tensión puede ser diferente, porque eso depende de la alineación del H con respecto al de la Tierra, en el sentido que dos tormentas similares pueden causar daños bien diferentes debido a este factor, en fin, guardo la guitarra. #sol #sun #solarstorm #geomagnetic #solarflare #solarcme #cme #coronalmassejection #eyecciondemasacoronal #climaespacial #spaceweather #radio #hamradio #dst

“This is an unusual and potentially historic event.” — Clinton Wallace
Director, NOAA’s Space Weather Prediction Center

A rare severe geomagnetic storm watch is issued for the first time in nearly 20 years amid "unusual" solar event.

CBS News quotes the U.S. National Oceanic and Atmospheric Administration (NOAA): "Geomagnetic storms can impact infrastructure in near-Earth orbit and on Earth's surface, potentially disrupting communications, the electric power grid, navigation, radio and satellite operations."

#SolarFlares, #Spaceweather via Spaceweather.com And there's a reason I held onto my eclipse glasses. Read on...

"THIS SUNSPOT IS HUGE: Sunspot #AR3664 has grown so large, it is now visually rivaling the great #Carrington sunspot of Sept. 1859. To illustrate their similarity, Carrington's famous sketch (to scale) has been added to a picture of today's sun:

"How big is AR3664? Sprawling almost 200,000 km from end to end, it is 15 times wider than Earth. You can see AR3664 through ordinary eclipse glasses with no magnification at all. Moreover, it is easy to project an image of this sunspot onto the sidewalk or a white screen just as Carrington did in the 19th century.

"Carrington's sunspot is famous because in August and Sept. 1859 it emitted a series of intense #SolarFlares and #CMEs. The resulting #geomagnetic storms set fire to telegraph offices and sparked auroras from Cuba to Hawaii. The '#CarringtonEvent' has since become a touchstone of space weather in pop culture, with headlines stoking fears of an "internet apocalypse" if it repeats. Recent studies suggest that Carrington-class storms occur once every 40 to 60 years, so we're overdue.

"Does this mean we're about to get hit by another Carrington Event? Probably not. Big sunspots don't always produce big CMEs. Indeed, the CME AR3664 hurled toward us earlier today is puny compared to the CMEs of 1859. It won't cause much trouble when it arrives this weekend. Nevertheless, it would be wise to keep an eye on this growing active region while Earth is in its strike zone."

Potential Impacts: Area of impact primarily poleward of 50 degrees Geomagnetic Latitude.
Induced Currents - Power system voltage irregularities possible, false alarms may be triggered on some protection devices.
Spacecraft - Systems may experience surface charging; increased drag on low Earth-orbit satellites and orientation problems may occur.
Navigation - Intermittent satellite navigation (GPS) problems, including loss-of-lock and increased range error may occur.
Radio - HF (high frequency) radio may be intermittent.
Aurora - Aurora may be seen as low as Pennsylvania to Iowa to Oregon.

I just read more about geomagnetic storms, gas and plasma bursts coming ejected by our sun.

I did not really like the possible outcomes and likelyhood of such events. G5 sounds like it can mess up our daily life big.

Today European Space Agency (#ESA)'s #Swarm constellation which measures Earth's magnetic field , celebrates 9 years since launch.

We used Swarm data to study #migratory #bird #navigation. We first linked Swarm data to #GPS #trajectories of migratory birds:
https://movementecologyjournal.biomedcentral.com/articles/10.1186/s40462-021-00268-4

Then we developed new models of #geomagnetic #navigation:
https://www.sciencedirect.com/science/article/pii/S157495412200139X

This is the first time anyone used data on real geomagnetic conditions to do this! And it could not have happened without Swarm.
