Sunspot 1166 Launches a Massive Flare

Sunspot group 1166 was the site of an X1.6 class flare about an hour ago (12:00 pm). This is a pretty significant flare, and should be sufficiently aligned with Earth to have a good chance of producing aurora. Currently the only warning from the Australian IPS is for a chance of activity today from the flares of yesterday from Sunspot Group 1164. See also Spaceweather.

We will have to wait a little while to see if this flare will have the potential for aurora.

UPDATE via Spaceweather:
Newly-arriving coronagraph data from the Solar and Heliospheric Observatory show no bright CME emerging from this eruption. Some material was surely hurled in our direction, but probably not enough for significant Earth-effects.

solar flares are significantly cool.
