Some - called diffuse aurora - are more like an even glow dispersed throughout the sky.May 26, 2021 - Scientists know a fair bit about these diffuse auroras, but an old video from 2002 revealing what seems to be an undocumented auroral phenomenon shows we definitely don't know everything....

Those who happened to look outside that evening, were rewarded with an amazing spectacle. However, by sunset on Sunday, the chance of aurora had subsided, leaving many hopeful viewers in the dark. What happened? Why are auroras so hard to predict, and how reliable are aurora forecasts? To...
The auroras occur in the ionosphere.The ionosphere is the layer of the upper atmosphere where high- energy solar radiation strips electrons from oxygen and nitrogen atoms, and leaves them as positively charged ions.The auroras are the result of a complex interaction between the solar wind and the...
Solar storms are immense clouds of charged solar particles that sweep out through the solar system. When one passes by Earth, these charged particles interact with the planet's magnetic field, causing a disturbance known as a geomagnetic storm, which can result in bright aurora d...
But the aurora-causing solar flares and coronal mass ejections currently spewing from the sun are a result of the same sunspots that triggered solar activity in May, according to Dr. Ryan French, solar physicist at the National Solar Observatory in Boulder, Colorado. Ad Feedback Coronal mass e...
Besides the pulsed reconnection mechanism which explains the PMAFs in terms of newly merged magnetic field tube, there are two other possible mechanisms. One of those is based on the presence of a gap between the central plasma sheet and the LLBL / magnetopause. This means that the dayside ...
where thin-current-sheet conditions are conducive to reconnection. The dayside magnetodisc is usually considered thicker than the nightside due to the compression of solar wind, and is therefore not an ideal environment for reconnection. In contrast, a recent statistical study of magnetic flux circula...
