Solar flares are seen as bright regions in images observed by AIA onboard SDO. The intense electromagnetic radiation causes low frequency and HF communication problems.

AIA 211 Å, 193 Å, 171 Å
This image combines three images with different, but very similar, temperatures. The colors are assigned differently than in the single images. Here AIA 211 is red, AIA 193 is green, and AIA 171 is blue. Each highlights a different part of the corona.

GOES 16 (NOAA)

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.

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.

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. There are some gaps in the data from different satellites and more details on the chronology can be found at: http://sxi.ngdc.noaa.gov/sxi_data_notes.html and http://sxi.ngdc.noaa.gov/

Curated SUVI images and animations processed at the National Centers for Environmental Information (NCEI) are available at:

Older SXI image data from GOES 12-15 are in the process of being made available at this site, but are also available at:

GOES 17 (NOAA)

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.

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.

Solar Farside (SDO)

Info:
The far-side image display the seismic signature of magnetic activity on the side of the Sun that we cannot directly see from Earth. Darker regions indicate locations where there is an accumulation of magnetic field.

NorthernLightsStockholm.se started as something to do, to stay sane in the cold and dark winter months in Sweden. But now i need your help to keep this project alive. There are numerous things that I am paying out of my own pocket to keep this up and running and i simply cannot afford it any more.

Just the electricity bill is going to be insane this winter. I might need to turn off the server!!!

I am asking for your help to pay for the following:
★ SSL certificates
★Domain & DNS
★Server hosting (when I can afford it)
★Internet service provider
★Development time
★Plug-ins and functions
★API services
