SantiagoPara 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. <a href="https://mastodon.uy/tags/sol" class="mention hashtag" rel="nofollow noopener" target="_blank">#sol</a> <a href="https://mastodon.uy/tags/sun" class="mention hashtag" rel="nofollow noopener" target="_blank">#sun</a> <a href="https://mastodon.uy/tags/solarstorm" class="mention hashtag" rel="nofollow noopener" target="_blank">#solarstorm</a> <a href="https://mastodon.uy/tags/geomagnetic" class="mention hashtag" rel="nofollow noopener" target="_blank">#geomagnetic</a> <a href="https://mastodon.uy/tags/solarflare" class="mention hashtag" rel="nofollow noopener" target="_blank">#solarflare</a> <a href="https://mastodon.uy/tags/solarcme" class="mention hashtag" rel="nofollow noopener" target="_blank">#solarcme</a> <a href="https://mastodon.uy/tags/cme" class="mention hashtag" rel="nofollow noopener" target="_blank">#cme</a> <a href="https://mastodon.uy/tags/coronalmassejection" class="mention hashtag" rel="nofollow noopener" target="_blank">#coronalmassejection</a> <a href="https://mastodon.uy/tags/eyecciondemasacoronal" class="mention hashtag" rel="nofollow noopener" target="_blank">#eyecciondemasacoronal</a> <a href="https://mastodon.uy/tags/climaespacial" class="mention hashtag" rel="nofollow noopener" target="_blank">#climaespacial</a> <a href="https://mastodon.uy/tags/spaceweather" class="mention hashtag" rel="nofollow noopener" target="_blank">#spaceweather</a> <a href="https://mastodon.uy/tags/radio" class="mention hashtag" rel="nofollow noopener" target="_blank">#radio</a> <a href="https://mastodon.uy/tags/hamradio" class="mention hashtag" rel="nofollow noopener" target="_blank">#hamradio</a> <a href="https://mastodon.uy/tags/dst" class="mention hashtag" rel="nofollow noopener" target="_blank">#dst</a>

The '<a href="https://kolektiva.social/tags/CarringtonEvent" class="mention hashtag" rel="nofollow noopener" target="_blank">#CarringtonEvent</a>' 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."<a href="http://www.spaceweather.com" rel="nofollow noopener" translate="no" target="_blank">http://www.spaceweather.com</a>
