What is the predicted duration of this enhanced aurora activity?

Experts predict this period of enhanced aurora activity will continue through 2027, even though the sun may be waning from solar maximum in late 2024. This extended period is due to the lingering effects of increased solar activity.

Northern Lights Display Predicted for May 28, 2025

A G1-rated geomagnetic storm is predicted for May 28, 2025, potentially making the Northern Lights visible across 15 northern U.S. states and parts of Canada due to a coronal hole releasing high-speed solar wind with negative polarity, following an X1.1 solar flare and two smaller flares on May 25.

What caused the predicted geomagnetic storm, and what are its broader implications for space weather?

The geomagnetic storm, resulting from a coronal hole and high-speed solar wind with negative polarity, is predicted to cause aurora borealis displays with a Kp index of 5. This means the aurora will be brighter and more active, visible further from the poles than usual. The new moon on May 27 will enhance viewing conditions.

What were the intensity and origin of the May 14th solar flare, and what immediate effects are observable near Earth?

On May 14, 2025, the most powerful solar flare of the year occurred, registering 2.7 on the scale, classified as "extreme". This surpasses the previous strongest flare of 2.0 on February 23rd. The flare originated from a large sunspot initially dubbed a "sleepy monster" due to its unexpected calmness.

What are the optimal conditions for viewing and photographing the aurora borealis during this period of increased solar activity?

The aurora borealis visibility will depend on factors such as location, time, and light pollution. Optimal viewing conditions occur between 10 p.m. and 2 a.m. local time at high vantage points away from light sources. The increased solar activity, peaking in October, is responsible for this phenomenon.

What caused the current geomagnetic storm, and what is the severity level on the space weather scale?

The storm, triggered by a massive M8.2 solar flare and coronal mass ejection (CME) from the Sun, is causing temporary disturbances in Earth's magnetic field. This event highlights the vulnerability of our infrastructure to space weather, as evidenced by potential power fluctuations, satellite operation effects, and GPS disruptions.

Colossal Solar Hole Unleashes Geomagnetic Storm Toward Earth

A massive coronal hole, over 1 million kilometers wide, has opened in the Sun's atmosphere, releasing a solar wind stream toward Earth, potentially causing geomagnetic storms from May 20-22 and a possible stronger storm on May 23; the cause is the current solar maximum.

What is the cause of this coronal hole and its associated solar storm?

The coronal hole, facing Earth, is expected to cause geomagnetic storms from May 20th to 22nd, possibly extending auroras to lower latitudes. A coronal mass ejection (CME) might hit Earth's magnetic field on May 23rd, potentially intensifying a minor (G1) geomagnetic storm.

What caused the unusually widespread auroral displays of May 10-11, 2024, and what were the immediate consequences?

On May 10-11, 2024, an unusually intense geomagnetic storm caused auroras visible as far south as Mexico and west Africa, and as far north as Australia, Chile, and Argentina. This was due to five coronal mass ejections following powerful solar flares. The event prompted NOAA to consider revising the geomagnetic storm scale.
