TAIPEI (Taiwan News) — The Central Weather Administration issued a geomagnetic disturbance alert at 5 a.m. Tuesday, warning that activity is likely to intensify over the next 39 hours and could develop into a moderate geomagnetic storm.

The disturbance stems from a significant solar flare, a coronal mass ejection, that erupted Sunday in an active region of the sun. The event is expected to increase the speed and density of solar wind in interplanetary space and temporarily disturb the Earth’s magnetic field, per CNA.

Such conditions can affect satellite navigation, disrupt orbits that later require correction, and cause brief interruptions in low-frequency and high-frequency radio communications.

The CWA’s Space Weather Operational Office said the effects are expected to reach near-Earth space on Tuesday. It said auroral activity may be visible at magnetic latitudes as low as 50 degrees.

The office added that some satellite equipment may experience electrical charge buildup, while low Earth orbit satellites could face increased atmospheric drag, potentially requiring additional altitude adjustments.
