Looking Up - Solar Storms This Weekend -- UPDATED

Three of our community had sent in submissions regarding the solar storms expected to arrive over the weekend. Auroras, weather permitting, will be visible over much of the northern hemisphere. For those of you who like to see such things, or for those of you looking for something different to do, why not get outside and take a look:

Updated flare status

For the first time since October 2003, G5 conditions have been observed. This is described as an extreme geomagnetic storm and is the highest level on NOAA's scale for geomagnetic storms. In addition to reaching G5 conditions, an S2-level solar radiation storm was observed today, and HF radio blackouts at the R3-level have occurred multiple times.

If you're hoping to see auroras, NOAA provides real-time short-range ~30-60 minute forecasts of auroral activity in both the northern and southern hemispheres. There is also a separate dashboard for monitoring disruptions to HF radio.

Earth prepares for solar storm impact from three CMEs this weekend

Solar activity has reached high levels in the past 24-36 hours, with background flux at or near M1.0. The most significant developments from the Sun include the growth and merging of Regions 3664 and 3668, as well as the production of numerous M-class solar flares and two X-class solar flares from CMEs that are expected to arrive at Earth this weekend.

A particularly volatile sunspot has sent a series of solar storms surging toward the Earth, many of which are due to hit in the next few days.

Sunspot AR3663 released five plumes of solar plasma-coronal mass ejections, or CMEs-in the past day, with the second, third, and fifth being forecast to slam directly into our planet this weekend.

This could lead to "strong" geomagnetic storms in our magnetic field and atmosphere, which could result in auroras being seen as far south as Illinois and Oregon.
