X1.5 Solar Flare Alert Update!!!!

X-FLARE: March 9th ended with a powerful solar flare. Earth-orbiting satellites detected an X1.5-class explosion from behemoth sunspot 1166 around 2323 UT. A movie from NASA's Solar Dynamics Observatory shows a bright flash of UV radiation plus some material being hurled away from the blast site:

After four years without any X-flares, the sun has produced two of the powerful blasts in less than one month: Feb. 15th and March 9th. This continues the recent trend of increasing solar activity, and shows that Solar Cycle 24 is heating up. NOAA forecasters estimate a 5% chance of more X-flares during the next 24 hours. Stay tuned.

Space weather for the past 24 hours has been strong. 
Solar radiation storms reaching the S1 level occurred. Radio blackouts reaching the R3 level occurred.
Solar activity is expected to remain moderate for day 1 (10 March) with a chance for M-class activity from Region 1166 or Region 1169.
The geomagnetic field is expected to be unsettled to active, with isolated minor storm periods possible at high latitudes on day one (10 March), and primarily unsettled conditions on days two and three (11-12 March). The CME from 07 March is expected to arrive mid-day on 10 March, leading to the elevated activity.

Stay tuned for more information.
