Alert for solar storm
A large Coronal Mass Ejection (CME) burst onto the Sun's surface on March 17. This CME is currently headed towards Earth and has the potential to cause a solar storm by igniting a geomagnetic storm in the near future. This occurred only a few days after a mild G1-class geomagnetic storm was caused by another CME that touched Earth's magnetic field. Read up on this solar storm warning in full.
NASA's Solar Dynamics Observatory captured a massive explosion of the solar surface where a CME was ejected, according to a SpaceWeather article. It is said that this CME is a "Canyon of Fire." Based on data modelling, the space agency has determined that Earth is currently being approached by this solar storm cloud.
Since this CME is now predicted to approach Earth's magnetic field on March 20 and may potentially trigger a G1-class geomagnetic storm, forecasters have issued a solar storm notice.

Moreover, the research indicates that auroras may be produced in high latitudes by this geomagnetic storm, particularly on the first night of the Northern Spring.
The study claims that on March 20, our planet's magnetic field might be slightly affected by yesterday's "canyon of fire" CME (explained below). If so, equinox auroras would be perfectly timed. This time of year, the springtime Russell-McPherron effect allows even a passing strike from a CME to trigger geomagnetic storms.
Regarding the effect of Russell-McPherron
Now that the Vernal Equinox has arrived, the Russell-McPherron effect is activated. Day and night have the same length during this period because the Sun is directly overhead the equator. Furthermore, a semiannual change in the interplanetary field's effective southerly component is noted.
