(YELLOWKNIFE, NORTHWEST TERRITORIES) When a geomagnetic storm is in the forecast (today, for example), a network of Northern Lighthouses in Yellowknife will flash Red and the latest storm watch information will be posted on northernlighthouse.ca. Astronomy North’s newest website provides important information for storm chasers, including CME Arrival Time predictions, storm forecasts, real time oval data and more. It’s also a great place to learn more about space weather and the world’s first street level early warning system for Northern Lights! Check it out!
HEADING OUR WAY • A major X1.2-Class solar flare erupted near Active Region 1944 on Tuesday (see below) while Earth in the direct line of fire. This long-duration flare launched a Coronal Mass Ejection (CME) in the direction of Earth. Current CME Arrival Time Predictions (above) show this massive burst of solar wind is due to arrive at Earth’s magnetic field early on Thursday (or possibly late Wednesday night). A direct hit from this fast-moving gust of solar wind is likely to trigger G1-G2 geomagnetic storming on Thursday and Friday. Stay tuned for more information as events unfold! Observers across Canada should be on alert for auroras early on Thursday morning.
UPDATE: Wednesday, January 8 @ 8:00 a.m. MST
PREDICTION UPGRADED TO POSSIBLE G3 (STRONG) • The latest analysis of the incoming CME indicates the incoming gust of solar wind is moving very fast and is likely going to be a direct hit when it blows past Earth early on Thursday morning (current arrival time prediction from NOAA is 1 a.m. Continue reading
HEADS UP, AURORA FANS! Massive AR1944, one of the largest sunspot regions of Solar Cycle 24, is now in a geoeffective position and is harbouring plenty of energy (capable of producing M-Class and X-Class flares). Sunday’s long-duration M4-Class solar flare from this region resulted in a coronal mass ejection that could deliver a glancing blow to Earth’s magnetic field early on January 7, which means observers across the North should be on alert for active auroras Monday, Tuesday and Wednesday of this week. With more eruptions possible in the days ahead, space weather forecasters will be watching the Sun very closely. (Image by SOHO).

MAJOR SOLAR FLARE! A major X-1.2 Class solar flare erupted Tuesday near region 1943, in close proximity to AR1944! We are awaiting additional information about a possible Earth-directed coronal mass ejection and what the implications will be for geomagnetic activity in the days ahead. Stay tuned!
