Storm Category: G1 (Minor)
Watch Begins: Tuesday, February 16, 2016
17:00 MST

Duration: 48 Hours

Storm Watch Details:


ONGOING EFFECTS 
• The delayed arrival of an Earth-directed Coronal Mass Ejection (CME) on Tuesday in conjunction with a high-speed solar wind stream has triggered steady geomagnetic storm activity since Monday, and the latest data suggests that G1 (Minor) storming will be possible again on Wednesday and Thursday. The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center has issued a 48-hour storm watch that will take effect at 5 p.m. MT on Tuesday, February 16. For the latest visualization of the solar wind stream, check out the CME Arrival Time Prediction web page.

Watch Begins: Saturday, February 13, 2016
17:00 MST

Duration: 48 Hours

Storm Watch Details:


INCOMING CME
• The arrival of an Earth-directed Coronal Mass Ejection (CME) on Sunday evening is expected to trigger G1 (Minor) geomagnetic storm activity overnight on Valentine’s Day, with a possibility of unsettled and stormy conditions continuing on Monday evening as well. The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center has issued a 48-hour storm watch that will take effect at 5 p.m. MT on Saturday, February 13. For the latest visualization of the incoming gust of solar wind, check out the CME Arrival Time Prediction web page.

STORM WATCH

Storm Category: G1 (Minor) – G3 (Strong)
Watch Begins: Tuesday, December 29, 2015
17:00 MDT

Duration: 48 Hours

Storm Watch Details:


INCOMING CME 
 A Coronal Mass Ejection (CME) that erupted from Sunspot AR2473 on December 28 is expected to sweep past Earth on Wednesday, December 30 with enough force to trigger G3 (Strong) Geomagnetic Storm conditions. Solar wind speeds are expected to reach and sustain 600 km/sec for many hours following the initial impact, which is predicted to occur Wednesday morning (+/- 6 hrs). The elevation of solar wind speeds for an extended period of time could be unsettling enough to trigger multiple geomagnetic storms over a 24-hour period. The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center has issued a 24-hour G3 (Strong) storm watch that will take effect on Tuesday December 29 at 5 p.m. Mountain Time, followed by a 24-hour G1 (Minor) storm watch that will take effect on Wednesday December 30 at 5 p.m. Mountain Time. For the latest visualization of space weather conditions in the coming days, visit the CME Arrival Time Prediction web page. Observers in YT NT NU AB SK MB and northern BC ON QC NL NB should be on alert for active auroras early Wednesday morning as well as Wednesday evening and overnight if storm conditions persist.
