A lot of aurora enthusiasts have put 17 May in their agenda as a possible date for some enhanced geomagnetic activity and thus auroral displays. Why? Because that is the date that a coronal hole solar wind stream is expected to arrive at Earth from a coronal hole that managed to give us moderate G2 geomagnetic storm conditions back in April.
A lot of people come to SpaceWeatherLive to follow the Sun's activity or if there is aurora to be seen, but with more traffic comes higher server costs. Consider a donation if you enjoy SpaceWeatherLive so we can keep the website online!
