Stealth Solar Storm Surprises Scientists
A sneaky solar storm surprised scientists by quietly reaching Earth.
These 'stealth' storms are hard to spot and can cause auroras and other space weather effects.
They're more common when the Sun is less active.
A solar storm reached Earth on November 20 without warning signs
Stealth solar storms are unusual, hard-to-detect coronal mass ejections (CMEs)
This event may have contributed to visible auroras in mid-latitude regions
Scientists detected the storm through unusual solar wind patterns and magnetic field changes
Stealth CMEs are more common during the waning phase of the Sun's 11-year activity cycle
