[quote:Anonymous Coward 11198416:MV8xMzgyOTUyXzI5OTMzNDczX0NBQTU4MzFF] [b]Joint USAF/NOAA Report of Solar and Geophysical Activity 4 March 2012 2200 UTC[/b] [b]Analysis of Solar Active Regions and Activity from 03/2100Z to 04/2100Z:[/b] Solar activity was moderate. [color=red]A long duration M2/1N flare was observed [/color]at 04/1052Z from [color=red]Region 1429 (N18E55).[/color] Associated with the event[color=red] was a 750 sfu Tenflare, Type IV Radio Sweep, and a CME first visible in STEREO B COR 2 Imagery at 04/1210Z[/color] [color=red](estimated speed of 840 km/s).[/color] This region is classified as a[color=red] Dkc spot group with a Beta-Gamma-Delta magnetic configuration.[/color] [color=red]Further analysis of the CME will be necessary [/color]as imagery becomes available, however [color=red]there appears to be a partial Earth-directed component.[/color] A glancing blow is possible from this event. [b]Solar Activity Forecast: [/b]Solar activity is expected to be at low to moderate levels with a [color=red]slight chance for an [b]X-class[/b] flare from Region 1429.[/color] [b]Geophysical Activity Summary 03/2100Z to 04/2100Z:[/b] The geomagnetic field was at quiet to active conditions with an isolated major storm period observed at high latitudes between 04/0900 - 1200Z. Activity was due to extended periods of the negative Bz component of the interplanetary magnetic field near -5 nT. The solar wind speed at the ACE spacecraft was relatively steady near 380 km/s. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during the period. [b]Geophysical Activity Forecast: [/b]The geomagnetic field is expected to be mostly quiet on day 1 (05 March). Activity levels are expected to [color=red]increase on day 2 (06 March) due to a possible glancing blow from today's CME associated with the M2/1N flare.[/color] Unsettled to active conditions are expected with isolated minor storm periods possible. Conditions are expected to settle down to mostly quiet to unsettled conditions by day 3 (07 March) as the effects of the CME wane. [b][color=red]There is a slight chance for a greater than 10 MeV proton event from Region 1429 for the forecast period.[/color][/b] [b]Event Probabilities 05 Mar-07 Mar Class M 60/60/60 Class X 15/15/15 Proton 15/15/15[/b] http://www.spaceref.com/news/viewsr.html?pid=40137&utm_campaign=&utm_medium=srs.gs-twitter&utm_source=t.co&utm_content=api :ohyeah: [/quote]

We have just had another huge X flare measuring at a X8.2 originating from sunspot 2673
On September 11, 2017
[

ALL flares recorded ARE Earth facing regardless of where the sunspot is located
-----------
CME FROM X9 HAS ARRIVED!
Issue Time: 2017 Sep 07 2242 UTC
WARNING: Geomagnetic Sudden Impulse expected
Valid From: 2017 Sep 07 2255 UTC
Valid To: 2017 Sep 07 2330 UTC
IP Shock Passage Observed: 2017 Sep 07 2229 UTC
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!
