..maybe something interfering with view but since I have had so many incoming solar feels thought to post it see what if anything is reported later. https://services.swpc.noaa.gov/images/animations/suvi/primary/195/latest.png This next one unless I misunderstand it is saying it's a coronal hole...it's gargantuan....if so something is going to be blown away...yikes.  |

Must have been a satellite obstruction. |

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. |

more explanation on the ultraviolet images ... EXCERPT: The Solar Ultraviolet Imager is a telescope that monitors the sun in the extreme ultraviolet wavelength range. By observing the sun, SUVI is able to compile full disk solar images around the clock. It replaces the GOES Solar X-ray Imager (SXI) instrument and represents a change in both spectral coverage and spatial resolution over SXI. -SUVI observes and characterizes complex active regions of the sun, solar flares, and the eruptions of solar filaments which may give rise to coronal mass ejections. Depending on the size and the trajectory of solar eruptions, the possible effects to near-Earth space and Earth’s magnetosphere, referred to as space weather, can cause geomagnetic storms which disrupt power utilities, communication and navigation systems, and may cause radiation damage to orbiting satellites and the International Space Station. -SUVI observations of solar flares and solar eruptions can provide early warning of possible impacts to Earth’s space environment and enable better forecasting of potentially disruptive events on the ground. SUVI is located on the Sun-Pointing Platform (SPP) of the satellite, which is located on the solar array yoke. The SPP provides a stable foundation and will track the daily and seasonal movement of the sun which is critical to the success of SUVI. Data from SUVI provides an estimation of coronal plasma temperatures and emission measurements which are important to space weather forecasting. SUVI is essential to understanding active areas on the sun, solar flares and eruptions that may lead to coronal mass ejections which may impact Earth. Depending on the magnitude of a particular eruption, a geomagnetic storm can result that is powerful enough to disturb Earth’s magnetic field. Such an event may impact power grids by tripping circuit breakers, disrupt communication and satellite data collection by causing short-wave radio interference and damage orbiting satellites and their electronics. SUVI helps the NOAA Space Weather Prediction Center provide early space weather warnings to electric power companies, telecommunication providers and satellite operators. |

thanks. this information will tell us when we lose our communications. we will have to talk to one another personally. |
