Solar activity over the last 24 hours has been **moderate**, with 21 flares recorded. Â

**NOAA’s dashboard** predicts a 60 percent chance of radio blackouts till Friday. Â

**Solar radiation storms** pose a 10 percent risk, endangering satellites and astronauts. Â

These storms occur when **charged particles** are accelerated near the sun. Â

They can disrupt **satellite communications** and pose radiation hazards. Â

The **northern hemisphere** might witness stunning auroras this week. Â

Currently, the sun boasts **eight active sunspots** on its Earth-facing side.Â

**NOAA** warns regions 3691 and 3697 could unleash potent flares. Â
