SOLAR WIND PREDICTIONS • Two Coronal Mass Ejections are expected to impact Earth’s magnetic field this weekend, as illustrated by the WSA-Enlil Solar Wind Prediction Model.
(YELLOWKNIFE, NORTHWEST TERRITORIES) Observers across the North should be on alert for G1 (Minor) and G2 (Moderate) geomagnetic storms this weekend. Space weather forecasters are predicting Earth will be impacted by multiple Coronal Mass Ejections, large gusts of solar wind that erupted near Sunspot AR2241 during M-Class solar flare events on Wednesday and Thursday.
WHERE TO LOOK • The apparent origin of Monday’s Leonid Meteor Shower is the constellation Leo, located just below the Big Dipper. The stars of Leo (along with Jupiter) will rise in the east just after midnight, followed by a crescent moon at 3 a.m. MT.

(YELLOWKNIFE, NORTHWEST TERRITORIES) Dark skies and the relatively feeble light from a waning crescent moon will set the stage for a promising Leonid meteor shower on Monday, November 17. The actual peak of the shower will occur before dark, however observers at high latitudes in North America can still expect to see 10-15 meteors per hour in the eastern sky late evening, shifting to the southeastern sky overnight.
Earth is encountering the dusty remnants of comet Tempel-Tuttle, a periodic comet that was discovered in 1865 and orbits the Sun every 33 years. As Earth passes by we see the orbital path of the comet is oriented near the constellation Leo, found just below the Big Dipper. Leo will rise in the east near midnight, accompanied by nearby Jupiter and a crescent moon. Continue reading
NOAA’s WSA-Enlil Solar Wind Prediction Model shows a gust of solar wind is expected at 09:00 UT on Monday, November 10 (2 a.m. MT).

(YELLOWKNIFE, NORTHWEST TERRITORIES) Northern skywatchers should be on alert for active auroras early Monday morning following the arrival of a Coronal Mass Ejection, a wave of particles from Friday’s X-Class eruption that is capable of triggering minor or moderate geomagnetic storms, activity that could add plenty of wobble to Earth’s magnetic field for days.
Forecasters at the the Space Weather Prediction Center have issued a 24-hour G2 (Moderate) Geomagnetic Storm Watch that begins on Sunday night at 6 p.m. MT followed by a 24-hour 24-hour G1 (Minor) Geomagnetic Storm Watch that begins on Monday night at 6 p.m. MT.
(YELLOWKNIFE, NORTHWEST TERRITORIES) Northern skywatchers can enjoy a red moon with their orange juice and toast on Wednesday morning as our lunar neighbour meets Earth’s shadow for the second time this year. This week’s lunar eclipse will get under way at approximately 2:45 a.m. MDT on October 8, and will last for almost five hours. Continue reading
