Get ready for some solar fireworks! 🌞🌌
NOAA's space weather forecast is here to prepare us for the upcoming celestial spectacle. The table below reveals the anticipated impact of two coronal mass ejections (CMEs) that erupted from the Sun on November 7th and 9th.
But first, let's decode the key terms:
- R, S, and G: These are the NOAA Space Weather Scales, measuring the severity of space weather events. R is for Radio Blackouts, S for Solar Radiation Storms, and G for Geomagnetic Storms.
- R1-R2, R3-R5, S1 or greater: These indicate the intensity of each category, with higher numbers representing more severe conditions.
Now, the forecast:
| Date | Radio Blackouts (R) | Solar Radiation Storms (S) | Geomagnetic Storms (G) |
| --- | --- | --- | --- |
| 10 Nov | R1-R2 | S1 or greater | G1 Watch |
| 11-12 Nov | R1-R2 | S1 or greater | G2 Watch |
And here's what to expect during these events:
- HF Radio Communication: Minor disruptions on the sunlit side, with occasional radio contact loss.
- Navigation: Brief intervals of low-frequency navigation signal degradation.
The G1 and G2 watches indicate potential issues with power grids and satellite operations, so operators, take note! But here's where it gets controversial: are we doing enough to prepare for these events? Share your thoughts below!
