Overview
- NASA’s Solar Dynamics Observatory captured the eerie-looking image on Oct. 28, with bright active regions forming the “eyes” and “nose” and a large coronal hole shaping the “mouth.”
- NOAA forecasters expect minor to moderate geomagnetic storm conditions between Oct. 28 and 29 as the high‑speed solar wind stream reaches near‑Earth space.
- Auroras could intensify and be seen farther south than usual in parts of the Northern Hemisphere, including areas of the northern United States and Scotland.
- Potential effects are expected to be limited, with forecasters noting possible brief disruptions to satellites, communications and power-system operations.
- The observation was made in the 193‑angstrom wavelength and echoes a similar SDO image from 2014, underscoring recurring solar patterns tracked since 2010.
