As I write, Earth directed solar wind blows at 559.3 km/second. High speed solar wind is credited to sunspot AR2803 –
Last night, Adrien Mauduit at Night Lights Films captured “Aurora at the Beach”, mesmerizing real time aurora majesty washed in waves tickling a stony beach. Treat yourself to Aurora at the Beach, follow Adrien Mauduit at Night Lights Films. –
Below – screenshot of the current Aurora Oval illustrating the impact of high speed solar wind from AR2308. Centered at true magnetic North rather than geographical North Pole, the Aurora Oval widens or retreats at the command of space weather. Ovation Auroral Forecast – Auroral oval | SpaceWeatherLive.com is my go to aurora resource.
Geminid Borealis by Adrien Mauduit at Night Lights Films takes my breath away. Envious is an understatement. Oh to be perched on a peninsula in Norway witnessing the Geminids through tendrils of ethereal auroras.
No matter how long the work day, disheartening the news or lousy the weather, Adrien Mauduit at Night Lights Films never fails to put things right. Treat yourself to real time aurora majesty coupled with Mauduit’s innate instinct to nail the perfect musical accompaniment.
From Senja, Norway Adrien Mauduit of Night Lights Films captured ethereal timelapse of geomagnetic storms between September 25 – 28, 2020.
As I write Earth orbit passes through a stream of gaseous plasma erupting from a “hole” in the Sun. Solar wind rages at 610 km per second. Predicted to spew well into tomorrow, fair skies could see auroras as far south as Montana and Michigan.

Natural phenomenon needn’t be mysterious. Ponder Aurora Borealis, arguably one of nature’s greatest phenomenon, least mysterious spectacles. Aurora are offspring of space weather, nothing mysterious about that. On May 11, 2020 Earth is expected to cross a fold in the heliospheric current sheet. In less mysterious language – disruption of interplanetary space separating opposing magnetic polarities of Earth and Sun, briefly over riding Earth’s magnetic field, inviting solar energy to temporarily dazzle sky watchers with aurora majesty – consider yourself schooled in solar sector boundary crossing, a space weather basic.
Solar wind is the source of space weather. Just like Earth, the Sun has a magnetic field known as interplanetary magnetic field (IMF). Whipped into spiral rotation, wind driven IMF rotates in one direction dividing into spiral sections pointing to and away from the sun along an ecliptic plane ( direct line between Earth and the Sun). The edge of this swirling mass has a surface separating polarities of planetary and solar magnetism called the heliosphere current sheet.
Earth’s magnetic field points north at the magnetopause (the point of contact between our magnetosphere and the IMF). If the IMF happens to point south at contact the field link causes partial cancellation of Earth’s magnetic field – in other words, opening a temporary door for solar energy to enter our atmosphere. Welcome solar sector boundary crossing – a phenomenon born of high solar wind and coronal mass ejections (CME’s – aka solar flares).
Enough talk, time for dazzling aurora timelapse courtesy Adrian Mauduit at Night Lights Films –
Stay at home orders needn’t be defined by endless hours of television or Netflix. Consider using free time to embrace space weather, specifically Aurora Borealis. Start with https://spaceweather.com/ familiarize yourself with solar wind, sunspot numbers and current auroral oval. If favourable conditions suggest uppity auroras, find yourself a Aurora Cam.
Tonight into tomorrow, northern hemisphere sky watchers as far south as Iowa or Michigan to Washington State are on aurora alert. Auroras are caused by charged particles hitching a ride on solar wind, dark skies turn undulating curtains of mischievous colour when charged particles interact with molecules in our atmosphere. Usually, our magnetosphere acts as a planetary shield preventing geomagnetic interaction of charged particles. Every so often fast moving particles overwhelm our magnetic field, create an opening and light up night skies.
On May 12, a magnetic filament on the sun, seen here, became unstable and erupted. (NASA/SDO)
Since Monday, 3 additional solar eruptions sent fast moving charged particles our way. As a result the auroral oval (doughnut shaped ring around the pole where charged particles follow magnetic field lines, reason why far northern latitudes regularly witness geomagnetic storms), has shifted far to the south.

The colour of that light depends on the kind of molecule and the altitude of the collision.
Green is the most common colour, produced when the particles collide with oxygen at an altitude of around 100 to 300 km. At about 300 to 400 km, the interaction with oxygen produces red. Pink occurs below 100 km when nitrogen atoms are struck.
Bottom line – Space Weather Prediction Centre forecasters say there’s a 75% chance of geomagnetic storm activity tonight. If your skies are clear, go outside. If she’s willing, Aurora will find you. Opportunities like this don’t come along every day.
On April 5 NASA scientists launched sounding rocket mission AZURE (Auroral Zone Upwelling Rocket Experiment) from Norway’s Andoya Space Center. Twin rockets deployed chemical tracers capable of allowing researchers to track the flow of neutral and charged particles during an active geomagnetic storm. Emergency service switchboards were inundated with UFO sighting hysteria – seems no one bothered to alert residents of AZURE’s chemical meddling.
Lights over Lapland webcam operator Chad Blakely captured the first chemical puffs. Video below from Adrien Mauduit documents the spectacle.
From Adrien Mauduit at the Aurora observatory, Senja Island, Norway on March 17, 2019…
“It all started at around 10:00pm LT. Almost nothing until then when all of a sudden a big band appeared in the south. Around 10:30pm LT, a very nice show happened with some colorful and fast moving coronas.”
