A U.S. government agency indicated that a less intense repeat of Saturday's strong solar storm was anticipated on Sunday.

The U.S. National Oceanic and Atmospheric Administration (NOAA) reported that "coronal mass ejections" (CMEs) – solar plasma clouds capable of causing disruptions to power grids and communication systems – would impact Earth's magnetic field and atmosphere until at least Sunday night.

On Saturday, the powerful solar storm dazzled the skies globally but resulted in only minor disruptions to electric grids, communications, and satellite positioning systems.

The Federal Emergency Management Agency (FEMA) stated that no significant impacts from the storms were reported across FEMA regions. The U.S. Department of Energy confirmed no noticeable effects on electric customers.

SpaceX's Starlink satellite internet service acknowledged degraded performance on Saturday and was investigating the issue. CEO Elon Musk assured that their satellites were managing well despite the pressure.

Vibrant Northern Lights in purple, green, yellow, and pink were observed worldwide, including in Germany, Switzerland, China, England, and Spain.

In the U.S., the solar storm on Friday pushed the auroras further south than usual, visible in areas like Fort Lauderdale and Fort Myers, Florida, as well as Midwestern states like Kansas, Nebraska, Iowa, and Michigan.

NOAA issued a rare severe geomagnetic storm warning after a solar outburst reached Earth on Friday afternoon, earlier than expected.

While the storm posed risks to power grids and satellites, NOAA emphasized that for most people, no action was needed, and the auroras were the remarkable outcome of space weather.

The recent solar activity, associated with a large sunspot, is part of the sun's natural 11-year cycle reaching its peak.
