With your citizen science observations, we’ve improved our map to provide you better alerts of aurora sightings near you, a more accurate view-line of where the aurora can be seen, and now included the Southern Lights!
We will explain the origins of one of more common measurements of geomagnetic activity, the Kp index, and compare it to the solar wind power that we talk about previously.
In our previous posts, we describe how the density, speed and magnetic field strength and direction of the solar wind are measured, what Bz is, and what those mean for the aurora. We also introduced a handy parameter called the solar wind power that combines all these measurements. Here, we provide more detail about the solar wind power that we use at Aurorasaurus.
