Fuertes llamaradas solares a fines de 2024 y comienzos de 2025

El Sol emitió una fuerte llamarada solar, que alcanzó su punto máximo a las 5:41 p. m. ET el 3 de enero de 2025. El Generador de Imágenes Solares Ultravioleta de la Administración Nacional Oceánica y Atmosférica (NOAA), que observa el Sol constantemente, capturó una imagen del evento.

Las erupciones solares son potentes explosiones de energía que pueden afectar a las comunicaciones por radio, las redes eléctricas y las señales de navegación, y suponer riesgos para las naves espaciales y los astronautas.

Esta llamarada fue clasificada como X1.1. La clase X indica las llamaradas más intensas, mientras que el número proporciona más información sobre su intensidad.

Llamarada clase X1.2

El Sol emitió una intensa llamarada, que alcanzó su punto máximo a las 6:39 a. m. ET del viernes 3 de enero. El Generador Solar de Imágenes Ultravioleta de la Administración Nacional Oceánica y Atmosférica de Estados Unidos, que observa al Sol constantemente, capturó la imagen que compartimos debajo.

Los datos aportados por el Observatorio de Dinámica Solar (SDO) de la NASA no están disponibles temporalmente debido a las inundaciones en el edificio que alberga el centro de datos de la misión. La imagen de arriba fue captada por el Solar Ultraviolet Imager (SUVI) a bordo del satélite GOES-East de la NOAA.

En tanto, el 29 de diciembre de 2024, el Sol emitió tres llamaradas solares intensas, con impacto máximo a las 2:18 a.m. ET, 11:14 p.m. ET, y 11:31 p.m. ET. El GOES Solar Ultraviolet Imager de la NOAA capturó imágenes de estas llamaradas.

Sun Releases Strong Solar Flare

#

The Sun emitted a strong solar flare, peaking at 5:41 p.m. ET on Jan. 3, 2025. The National Oceanic and Atmospheric Administration’s Solar Ultraviolet Imager, which watches the Sun constantly, captured an image of the event.

Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.

This flare is classified as an X1.1 flare. X-class denotes the most intense flares, while the number provides more information about its strength.

Solar flare X1.2

#

A class X1.2 solar flare was emitted by the Sun peaking at 6:39 a.m. ET on Friday, Jan. 3.

Data from NASA’s Solar Dynamics Observatory (SDO )is temporarily unavailable because of flooding in the building that houses the mission’s data center. The image above was captured by the Solar Ultraviolet Imager (SUVI) on board NOAA’s GOES-East satellite.

About GOES couple

We took this data from GOES’s page:

Usage

• The GOES 16 and 17 spacecraft each carry a sophisticated extreme ultraviolet (EUV) telescope called the Solar Ultraviolet Imager (SUVI). This telescope allows forecasters to monitor the Sun’s hot outer atmosphere, or corona. EUV photons are created in the million-degree plasma of the corona and are not visible from the ground, due to the absorption of the Earth’s atmosphere. Observations of solar EUV emission aids in the early detection of solar flares, coronal mass ejections (CMEs), and other phenomena that impact the geospace environment.

• EUV photons travel at the speed of light and are the first indication we receive at Earth of solar magnetic eruptions and associated flares. These high-energy photons cause changes to the Earth’s ionosphere and can result in significant degradation of radio communications, including complete black outs at some frequencies. The impacts begin only 8 minutes (time for light to travel from the Sun to Earth) after a flare.

• The early warning given when SUVI observes a solar eruption comes at least 15 hours before the associated CME arrives at Earth. This allows forecasters at SWPC to issue the appropriate watches, warnings, and alerts for geomagnetic storms.

Details

• The SUVI telescopes are mounted on the Sun-pointing solar array gimbals of the GOES weather satellites. These satellites are in geosynchronous orbits that allow continuous solar viewing, 24 hours/day, 7 days/week. The only exception to this is around equinox dates when the GOES satellites enter Earth’s shadow for up to one hour each day.

• Each SUVI collects a solar EUV image several times per minute, and the exposure settings follow a sequence that is optimized to observe three primary phenomena as they are reflected in the Solar atmosphere: coronal structures, active regions, and solar flares.

• SWPC presents the images and animations of the GOES SUVI instruments in near-real-time, and uses them in analyzing events and in issuing space weather watches, warnings, and alerts.

History

• SUVI has been providing operational observations since March 11, 2020. Earlier instruments - the Solar X-ray Imagers (SXIs) on GOES 12 through 15 - made observations from December 15, 2004 to March 11, 2020.
