The sun launched 10 M-class solar flares in 24 hours, with multiple CMEs heading toward Earth.
CMEs are expected to hit Earth on July 3 and July 5, causing geomagnetic storms.
Storms could reach G2 or G3 strength, making auroras visible in northern US states.
Space weather physicist Tamitha Skov described the activity as a 'machine-gun sun'.

The Sun reportedly emitted two X-class solar flares within seven hours.
The activity caused temporary radio outages on Earth.
The short interval between the flares made the event more significant than a routine solar update.
Even a brief disruption shows how space weather can quickly become an infrastructure issue.

DKIST captured unusually strong calcium II H and hydrogen-epsilon signals during the decline of a C-class solar flare.
Researchers say current flare-heating models reproduce some features but fail to explain others.
The finding could improve both solar physics and the study of flares on other stars.
