Powerful Solar Storm Causes Rare Southern Sightings of Northern Lights

A severe geomagnetic storm on April 23 caused aurora visible as far south as California, Texas, Arizona, New Mexico, and Arkansas.
Northern lights were visible in California's northern Sierra foothills on Sunday night due to a severe geomagnetic storm triggered by a solar flare on the sun on Friday afternoon.
The sightings of northern lights in back-to-back months are the product of the sun entering its most active phase during its 11-year cycle.
Increased instances of sun spots or eruptions on the sun create these spacial geomagnetic storms, which can disrupt the Earth’s magnetic field and shift the display of the northern lights toward the equator.
Geomagnetic storms can cause impacts on electrical infrastructure, but have very little effect on humans.
