We’re not sure whether to be amazed or alarmed.
A “massive” coronal hole that rotated toward Earth from May 28-31 was one of the largest such holes NASA says it has observed all year.
The amazing part is that NASA’s Solar Dynamics Observatory was able to capture some spectacular ultraviolet footage of the hole in the sun’s corona. (Watch in the video above.)
The potentially alarming part?
Coronal holes (dark, cold areas in the sun’s outermost atmospheric layer) are the sources of solar winds — streams of charged particles that travel at more than 1 million mph and can cause auroras and geomagnetic storms (worldwide disturbances of the Earth’s magnetic field) when they reach our planet.

The sun’s peak of solar activity this year will likely be the quietest seen in at least 100 years, say NASA scientists who watch Earth’s closest star daily.
Sunspot numbers are low, researchers said, even as the sun reaches the peak of its 11-year activity cycle. Also, radio waves that are known to indicate high solar activity have been very subdued.
“It’s likely to be the lowest solar maximum, as measured by sunspot ‘number,’ in more than a century,” wrote Joe Gurman, a project scientist for NASA’s sun-observing mission Stereo, or Solar TErrestrial RElations Observatory. The current sun weather cycle is known as Solar Cycle 24.
