Coronal hole faces Earth

But that is not all, we also have a trans-equatorial coronal hole facing our planet today. A high speed solar wind stream flowing from this coronal hole is on its way to our planet which could cause some nice auroral displays over the weekend . Minor G1 geomagnetic storm conditions are expected from this coronal hole solar wind stream late tomorrow (29 October) into the early hours of Sunday, 30 October.

Updated Kp-index and color scheme

A bit of housekeeping also: we are following the updated Kp-index and G-scale color scheme as layed out by the NOAA SWPC. The Planetary K-Index will show green Kp values of 4 or lower then follows the G-scale colors which begins with yellow for Kp5. Kp values will now also be displayed in decimal format (e.g., 1.33, 1.67, 2.00).
