Vor 4 Tagen · HF Radio: Weak or minor degradation of HF radio communication on sunlit side, occasional loss of radio contact. Navigation: Low-frequency navigation signals degraded for brief intervals.
Magnetogram: State of Earth's Magnetic Field. Variations in Earth's magnetic field are measured by magnetometers. Any strong and sudden variations (up or down) in the X component (uppermost graph) are indications of VHF radio-auroral activity (e.g. on 144 MHz when variations suddenly peak, say, 300 nT).
Vor 2 Stunden · R3 Event on 16 July 2024 from Region 3738. published: Tuesday, July 16, 2024 14:18 UTC. Departing Region 3738 produced an X1.9 (R3-Strong) flare that peaked at 9:26am EDT (1326 UTC). The flare was associated with radio signatures that suggest a coronal mass ejection (CME) was likely associated with this activity, but due to its far southwestern ...

Vor einem Tag · The ≥10 MeV Integral Flux WARNING includes the predicted level of activity based on the NOAA S-scale. Proton Event ALERTS are issued upon confirmation of ≥10 Mev or ≥100 MeV Integral Flux exceeding certain thresholds. Initial ALERTS for ≥10 MeV and ≥100 MeV energies are issued for integral flux reaching or exceeding 10 pfu and 1 pfu ...
Vor 2 Tagen · Scientists predict an increase in lightning frequency by 11-31% for every degree of global warming, according to the BBC's report. This is because warmer air can hold more moisture, about 7% more ...
