[quote:Helios Maximus:MV8xMzgyOTUyXzg0MjcwODEwXzcxMDkwOEEz] [b]Solar Activity 24 hr Summary...[/b] Solar activity reached low levels during the period. Region 2792 (S22E39, Bxo/beta) produced a C4/Sf at 14/1437 UTC with an associated Type II radio sweep with a shock velocity of 606 km/s. SDO/AIA 193 and 304 imagery indicated [b]ejecta escaped the visible disk at the peak[/b] of the event. SOHO/LASCO coronagraph imagery observed a CME from the SE limb associated with this event. Initial analysis indicated the CME is likely off the Sun-Earth line, however we await the results of a WSA-Enlil model run to verify this analysis. New Region 2793 (S16E60, Axx/alpha) produced a few B-class events, but was otherwise stable. .Forecast... Solar activity is expected to be very low on 15-17 Dec, with a chance for C-class flares all three days. A few tiny spots but lots of activity in the Southern Hemisphere. The Northern Hemisphere is overdue to join the cycle 25 party. Another strange fact--the 2 largest events came from the farside, an M1 & M4. Many mysteries await....

An update as to the arrival time of this CME will be added once all data has been reviewed.
The X9.3 flare is the 14th largest X flare ever recorded!
On September 4th we had 7 M flares from fast growing sunspot 2673, with at least 1 large dense Earth directed CME. This CME will arrive late in the day on Wednesday September 6th.
There is now a 25% chance for X flares over the next 24hrs & 71% chance for M flares
We have a Long Duration M2.4 Solar Flare starting
01:05 UTC July 14th 2017
There was a full halo CME observed with this solar flare. The associated CME is Earth Directed. See discussion on the last page for all updates!
