Ulysses's observations of solar wind speed as a function of helio latitude during solar minimum.Slow wind (≈ 400 km/s) is confined to the equatorial regions, while fast wind (≈ 750 km/s) is seen over the poles. [1]
A coronal hole high-speed stream produces increased solar winds that leave the Sun radially. "When a CH rotates to the center of the Sun (directly facing Earth), the elevated speed starts its ...
An aurora is a natural light display in the sky, especially in the high latitude (Arctic and Antarctic) regions, in the form of a large circle around the pole. It is caused by the collision of solar wind and charged magnetospheric particles with the high altitude atmosphere (thermosphere).
Active stars produce disturbances in space weather and, if strong enough, in their own space climate.Science studies such phenomena with the field of heliophysics, which is an interdisciplinary combination of solar physics and planetary science.
Photos show the sky lit up in red and purple, ... The northern lights are caused by interactions between the sun's solar winds and the Earth's protective magnetic field, ...
The ethereal audio reminds me of wooden wind chimes rattling as a mass of land shifts, perhaps during an earthquake. It brings to mind the cracking sounds of a moving glacier as well.
A geomagnetic storm is defined [5] by changes in the Dst [6] (disturbance – storm time) index. The Dst index estimates the globally averaged change of the horizontal component of the Earth's magnetic field at the magnetic equator based on measurements from a few magnetometer stations.
The sun is constantly sending out solar winds. At times, these geomagnetic storms have been known to knock power out here on Earth, as was the case in part of Canada in 1989 .
