A burst of solar activity at the end of June has drawn the attention of space weather forecasters around the world after a powerful eruption from the Sun briefly disrupted radio communications across parts of North America and the Pacific. While the interruption itself lasted only a short period, scientists are now focused on a much larger development moving through space behind it.The event originated from an active region known as sunspot AR4479, which released a powerful X-class solar flare on June 30. |
