Quando Usar o Explorador 3D da Escala de Tempestade Geomagnética pelo Índice Kp - Melhores Sessões e Limites

Last reviewed: 2026-07-29

Abra o Explorador 3D da Escala de Tempestade Geomagnética pelo Índice Kp quando quiser comparar um dia calmo (Kp 2-3) com a tempestade real G5 de maio de 2024, ou ver como a escala G da NOAA se relaciona com o número Kp.

Uma lição: dia calmo vs. supertempestade

Uma sessão começa em um Kp calmo de 2-3 para ver o anel de aurora estreito e uma leitura abaixo da escala G, depois salta para o caso G5 de maio de 2024 para ver o anel se expandir e o traço oscilar muito mais - a mesma escala, mostrando o quanto uma supertempestade real fica acima da atividade geomagnética comum.

Sessões que este explorador não atende

Sessões que esta página não atende são a consulta da leitura Kp/G ao vivo de hoje - use a própria página em tempo real da NOAA SWPC para isso - ou o mecanismo de emissão de luz por trás da própria aurora, que pertence ao Explorador 3D da Aurora. Para uma supertempestade histórica específica, veja o Explorador 3D do Evento Carrington; para a estrutura estática do campo, veja o Explorador 3D da Magnetosfera Terrestre. Siga os controles no guia passo a passo.

Why trust these tools

Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
