[quote:Helios Maximus:MV8xMzgyOTUyXzg2MDY3NjY5XzM3RUFBQUUx] [quote:Simple27:MV8xMzgyOTUyXzg2MDU3NzAwXzVFMEVBNTI0] [b]SUNSPOT DOUBLES IN SIZE:[/b] Northern sunspot AR2804 has doubled in size since yesterday. It is now an easy target for backyard solar telescopes and a growing threat for Earth-directed solar flares. https://www.spaceweather.com/ [imgur]https://imgur.com/m6WnfJ9[/imgur] [/quote] Yes, AR2804 looks much bigger now. It's been much quieter but I wouldn't rule out an M-flare at some point. In a few days it will on the far side. Latest HMI image: http://jsoc.stanford.edu/data/hmi/images/latest/HMI_latest_Int_4096x4096.gif [b]NOAA/SWPC-[/b] .24 hr Summary... Solar activity was very low. Multiple low level B-class flares were observed from Region 2804 (N18W46, Dsi/beta). Slight decay was observed in the intermediate spots of the region. Region 2805 (S22W41, Axx/alpha) continued to decay over the period. No Earth-directed CMEs were observed. .Forecast... Solar activity is expected to be at very low levels, with a chance for C-class flaring on 26-28 Feb.

ALL flares recorded ARE Earth facing regardless of where the sunspot is located

On September 6th we have had 2 X flares! A X2.2 at 09:10 utc & a secend larger flare just a few hours later of X9.3 at 12:02 utc. There is a large widespread Earth directed CME associated with this latest X flare as we can see here

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!
