Northern Lights: Next Chance for Aurora Across Boston Expected Wednesday A strong solar flare erupted from the sun on Monday, triggering a geomagnetic storm watch for Wednesday evening and creating an opportunity for the northern lights to be visible in New England for the third time this year. NOAA’s Space Weather Prediction Center classified the storm as a level G2, which is moderate on a five-point scale ranging from G1 (minor) to G5 (extreme). This level of activity could extend the visibility of the aurora as far south as the borders of Massachusetts, New Hampshire, and Vermont. Shawn Dahl, service coordinator for the Space Weather Prediction Center, noted that if the storm reaches G2 levels during favorable early evening or dark hours, the aurora could be seen in northern New England. The potential for the storm to escalate to a G3, strong geomagnetic storm, remains possible, which could bring the view line farther south and allow all of New Englanders to witness the phenomenon. The sun’s activity, though millions of miles away, has the potential to intensify. The flare, an M2.8-class event, followed a relatively quiet month on the sun, raising questions about the intensity of the solar minimum. However, the flare produced an Earth-directed eruption, suggesting the excitement might be justified. Solar flares release plasma known as coronal mass ejections (CMEs), which are plumes of solar material carrying magnetic fields. These CMEs are launched into space at speeds exceeding 1 million mph and travel through space, interacting with Earth’s magnetic field. When charged particles from the CMEs collide with oxygen and nitrogen ions in the upper atmosphere, they create the shimmering ribbons of light known as the northern lights or aurora borealis.#space_weather_prediction_center #aurora_borealis #shawn_dahl #solar_cycle_25 #northern_lights
