Space Weather Canada has issued a major geomagnetic storm watch effective until June 1st 10:00 a.m. EDT.
The National Oceanic and Atmospheric Administration (NOAA) has also issued a Geomagnetic Storm Watch from May 31 to June 1, 2024. This alert follows the detection of a coronal mass ejection (CME), a significant eruption of solar material, which is expected to hit Earth and increase geomagnetic activity.
NOAA says the storm, classified as a G2 level, might allow the aurora borealis to be visible across parts of the northern and upper Midwest United States, from New York to Idaho.
For Canada, this means that provided the sky is clear, people in western Canada, the Territories, Labrador, northern Ontario, and northern Quebec can see the aurora borealis.
Residents of Newfoundland, Maritime provinces, southern Ontario and Quebec locations south of the St Lawrence River may see it on the northern horizon.
The aurora borealis illuminate the northern skies with vibrant displays which form when the Sun emits charged particles, which Earth’s magnetic field, acting as a shield, redirects. The field lines, stretched and snapped back by the solar wind, propel these particles towards Earth. Colliding with atmospheric gases, they create luminous bursts akin to neon lights, resulting in the mesmerizing dance of colours across the sky.
When & How to See:
When:
Space Weather Canada‘s current major geomagnetic storm watch is in effect until June 1 10:00 EDT.
NOAA predicts the maximum geomagnetic activity between 6 p.m. and 6 a.m. CT.
Where & How to See:
To enjoy a clear view of Nothern Lights, you should choose a location free of light pollution. The relentless glow from city lights often masks the subtle luminance of low-intensity auroras, rendering them invisible against the urban backdrop.
To find reasonably dark areas near your location, check the Darkskyfinder map. Search for a park (or a safe place with no streetlights away from roads/traffic) within the areas coloured dark (mustard), yellow, green, blue, grey or black (transparent). Before travelling, please check the cloud cover.
What people are not understanding is that, although pretty, being able to see it this frequent means there are some dangers approaching our planet. Look into this more.
