Auroras could grace Earth’s skies once more in early June, thanks to the reappearance of the massive sunspot that caused May’s vivid displays. Here’s when to watch for the next auroral show around June’s new moon.
#### Key Dates and Events: – **Late May/Early June:** The sunspot, active region 3664 (AR3664), will re-emerge, facing Earth once more. – **June 6:** New moon provides optimal dark skies for aurora viewing.
#### Background: In May, Earth experienced its most powerful geomagnetic storm in over two decades, with auroras visible as far south as Florida and Mexico. This rare event was driven by five solar storms from AR3664, a sunspot over 15 times the width of Earth. Charged particles from the sun collided with Earth’s magnetosphere, creating stunning auroras.
#### Viewing Tips: – **Timing:** Watch for auroras in the nights surrounding June 6’s new moon. – **Location:** Seek dark, clear skies away from city lights.
#### Scientific Insights: The sun rotates approximately every 27 days, so AR3664 is set to face Earth again in late May. As it reaches the center of the sun from our perspective, the potential for solar weather increases, possibly leading to another auroral display.
#### Solar Activity: AR3664 continues to produce significant solar flares, with a notable X12 flare on May 20. The current solar cycle, approaching its maximum, suggests more frequent and powerful solar flares.
#### Future Opportunities: Even beyond June, increased solar activity during the solar maximum means more chances for aurora sightings. Stay informed about solar weather forecasts to catch these spectacular events.
For the best viewing experience, be prepared to venture to locations with minimal light pollution and clear skies around early June.
