Winter's Dawn: Celebrating the Solstice

The Winter Solstice, which occurred on December 21st, marks the shortest day and longest night of the year, signaling the official start of winter. Mary Walrath-Holdridge and Julia Gomez from USA TODAY explore the significance of this astronomical event and how it is celebrated across different cultures. The solstice, occurring when the North Pole is tilted furthest away from the sun, brings the least amount of daylight and the longest night. This year, the solstice fell on December 21st at 4:21 a.m. EST, marking the astronomical beginning of winter in the Northern Hemisphere. Historically, the Winter Solstice has been a time of celebration and reflection. Ancient civilizations, such as the Romans with their Saturnalia festival and the Norsemen with their bonfires, honored the return of the sun and the promise of longer days ahead. Today, people continue to observe the solstice with various traditions, including gatherings, feasts, and rituals that pay homage to the natural cycles of l...

Solar Storm Brings Northern Lights to Southern Canada and Beyond


 


A series of powerful solar storms recently graced the night skies, making the northern lights unusually visible even in regions far south. This dazzling display was caused by a geomagnetic storm, which not only illuminated Canada but also extended its colorful auroras to parts of the northern United States and Europe.

The Solar Storm Phenomenon

  • Solar storms occur due to the sun’s activity cycle, which spans approximately 11 years. During the solar maximum, more sunspots appear on the sun’s surface. These sunspots are cooler regions that appear black when observed through solar telescopes. However, they are more than mere spots—they represent an entanglement of magnetic fields that can erupt with a solar flare.

  • Often, solar flares are followed by a coronal mass ejection (CME)—a massive burst of charged particles carried along the solar wind. In this recent case, the sun produced a series of CMEs, which are now heading toward Earth. The U.S.-based National Oceanic and Atmospheric Administration (NOAA) issued a severe geomagnetic storm watch for our planet, the first in nearly two decades.

A Spectacular Light Show

  • Where can you witness the northern lights? If Earth lies in the path of these charged particles, they interact with our magnetic field and molecules in the upper atmosphere, resulting in the mesmerizing aurora borealis. During this recent geomagnetic storm, the northern lights were visible not only in Canada but also in parts of the northern United States and Europe.

  • Clear skies in various regions allowed people to witness this celestial spectacle. From Vancouver to southern Canada and even central British Columbia, the colorful auroras danced across the night sky. If you were lucky enough to see them, you could capture the magic by sharing your photos with bcphotos@cbc.ca.

A Weekend of Wonder

  • As the solar storm continued, scientists anticipated that the northern lights would continue to dazzle on Saturday night. However, it’s essential to note that while these auroras are awe-inspiring, the storm could also cause disruptions to communications over the weekend.

In summary, the recent geomagnetic storm brought the northern lights to unexpected latitudes, creating a celestial spectacle that captivated skywatchers across Canada and beyond. So, if you find yourself under clear skies during such an event, don’t miss the chance to witness this natural wonder
