The Spanish Space Agency launches a warning after intense photo voltaic ejection | Science | EUROtoday

The Spanish Space Agency (AEE) has warned this Sunday to house and land infrastructure operators “maintain surveillance” and “update forecasts with the most recent data of international agencies”, after registering, over the last hours, an intense photo voltaic exercise attributable to an ejection of excessive -speed coronal mass.

“During the last hours, intense solar activity caused by a high -speed coronal mass ejection (CME) has been registered, associated with a solar fulguration of class M8.2 originated in the active region AR4100. This CME impacted the Earth’s magnetosphere during the early hours 09:00 UTC ”, has transferred the AEE in a press release, collected by Europa Press.

This has expressed it, explaining that, based mostly on the KP scale – which is used to measure the worldwide geomagnetic exercise and is expressed in values ​​from 0 to 9 – the situations “have moderated slightly”, with the KP oscillating round 7.3 ″, though the prediction fashions point out “a high probability” that the exercise intensifies once more within the subsequent 24 hours.

The European Space Agency (ESA), of which Spain is a member by way of the AEE, continues to “actively” the occasion by way of its house local weather providers community and, for the second, “a danger situation is not expected”, which may happen if the KP index reaches the intense degree of 9.

A G4 degree geomagnetic storm

According to the Space Climate Prediction Center of the National Office of American Oceanic and Atmospheric Administration (NOAA) and ESA, the occasion has been categorised as “a G4 level geomagnetic storm on a scale that goes from G1 (minor) to G5 (extreme)”.

“These types of phenomena can have various effects, including alterations in high latitude electrical networks, disturbances in high frequency radio communications, possible temporary errors in satellite navigation systems and temporary satellite effects on low orbits due to the increase in thermospheric density,” he mentioned.

However, because the AEE has communicated, “so far, important anomalies have not been reported by satellite operators.” “The AEE, through ESA, will continue to collect information through the detailed monitoring of the situation to evaluate the changes that may occur,” he concluded.
