Sunspot 11 times larger than earth spotted from Oman
Muscat – Astronomers in Oman have observed the largest sunspot of 2025, capturing rare images of the massive dark patch on the Sun's surface, which measures more than 11 times the size of Earth.
The sighting was made by the Oman Society for Astronomy and Space (OSAS) on the morning of May 8 using specialised telescopic equipment positioned in the skies over Muscat. Identified as Sunspot 4079, the phenomenon is part of the heightened solar activity associated with Solar Cycle 25, the current phase in the Sun's 11-year magnetic cycle.
'This sunspot represents one of the largest phenomena we have documented in the current solar cycle,' said Wisal bint Salim al Hinai, Deputy Head of the Community Outreach Committee at OSAS.
'Capturing it from Oman is a remarkable scientific achievement that highlights our ongoing efforts to monitor space phenomena that directly impact Earth.'
Sunspots are regions of intense magnetic activity that appear darker because they are cooler than their surroundings. Sunspot 4079 offers astronomers important clues about solar flares and coronal mass ejections – bursts of solar energy that can interfere with satellite communications, GPS systems, and power grids on Earth.
According to Hinai, the observation helps scientists better understand the potential risks of solar storms. The latest surge in solar activity has already led to several disruptions.
In February, the Sun released an X-class solar flare, followed by a coronal mass ejection that triggered geomagnetic storms in April. These storms lit up skies with auroras in unusual latitudes and disrupted radio communications.
Solar Cycle 25, which began in December 2019, has exceeded earlier forecasts in terms of intensity.
