Three solar flares occurred over a 24-hour period this week. While we may not see them with a naked eye, they can affect Earth. Here's how.
On March 10, 1989, a huge solar flare caused a storm that surged the Quebec power grid, which was out of commission for eight long hours on a weekday morning, affecting about 6 million people.
A geomagnetic storm is heading to Earth, with the possibility to disrupt GPS and communications. It could also bring the northern lights to Northern California, much farther south than is typical.
The incoming solar storm arose from a strong flare near “Region 3500” on the Sun, scientists say. Solar storms are known to interfere with the Earth’s magnetic field and cause damages to ...
The solar storms of May 2024 (also known as 2024 Mother's Day solar storm [1] or Gannon storm in memory of Jennifer Gannon, [2] a space weather physicist [3]) were a series of powerful solar storms with extreme solar flares and geomagnetic storm components that occurred from 10–13 May 2024 during solar cycle 25.
A solar flare is a relatively intense, localized emission of electromagnetic radiation in the Sun's atmosphere. Flares occur in active regions and are often, but not always, accompanied by coronal mass ejections, solar particle events, and other eruptive solar phenomena. The occurrence of solar flares varies with the 11-year solar cycle.
A powerful solar flare has been hurled out of the Sun, and could cause disruption on Earth. The flare comes amid increasing solar activity that has brought a run of intense space weather in recent ...
The rapidly growing sunspot AR3663 became the most active spot of the 25th solar cycle. On 5 May alone, it emitted two X-class (strongest) flares and six M-class (medium) flares. Each of these flares resulted in a short-term but profound disconnection of the Earth's radio signal, resulting in signal loss at frequencies below 30 MHz. [95]
