A geomagnetic storm level G2 is in progress. Aurora is visible at high-latitudes.
An M4.4 flare peaked at 22h08 UT 10 Dec.
A 10.7cm radio burst and type II radio emission were observed, indicating the eruption of a CME (coronal mass ejection).

Geomagnetic conditions appear to have fully calmed down now. The solar radiation storm has also ended.
As far as the sun is concerned, the XRay flux has been down at C-levels since the X5.1 flare two days ago. The NOAA SWPC G3 storm watch will expire at midnight UT, and a G1 watch will be in place for tomorrow (14 Nov), due to the possibility of sub-storms.
The are no big flare players on the solar disc once AR4274 rotates around the limb, so you can have a chance to recharge the camera batteries.

The strong geomagnetic storms have triggered a "Grid Emergency" in New Zealand.
Transpower is acting to protect its power grid by shutting off key sections to prevent damage. Some areas of New Zealand may lose power temporarily.

We're still awaiting the arrival of the first CME. There is definitely a geomagnetic storm in progress, we are just not seeing much effect from it yet.
These graphs are from the ACE satellite at L1 (1 million miles sunward of the Earth). Once these graphs start to deflect strongly we'll have around 45 minutes to an hour of notice before it reaches Earth.

CME update
It's always dangerous to try to live-report events like this. It's looking like we're only just seeing the "hairy edge" of the first CME which was never well placed to strike a direct hit. The solar wind is pretty lack-lustre right now and it seems it won't cause as much impact as first thought. A small bump is now arriving at Earth but it's not looking very impressive.
The second CME may come within hours and should be a lot stronger. I'll probably not be awake for it.
Aurora is visible on a camera over Iceland now, fighting a bright moon.

First effects coming now at geostationary orbit as the magnetosheath is compressed at the Goes satellites by the CME. This first CME is not going to be the biggest.

Incoming geomagnetic storms:
Effects from the X flares on 9 & 10 Nov should arrive at Earth at around 20h UT this evening (11 Nov), according to Nasa's WSA-ENLIL Solar Wind Prediction model.
This morning's X5.2 flare is racing towards us at around 1,800km/s and should arrive around midday (UT) on 12 Nov. It's fast velocity means that it will begin to interact with the preceding CMEs as it reaches Earth, causing a likely very chaotic Geomagnetic storm.
NOAA predicts upto to G4 conditions on 12 Nov. As long as the magnetic Bz component of the storms is southwards, very strong aurora is possible.
Space Weather
A strong substorm is in progress at high latitudes. Aurora possible.
Magnetometers on the Goes satellites have dropped sharply, suggesting incoming turbulence in the solar wind. Further geomagnetic storming is likely tonight.

A major X1.1 flare peaked at 22h00 UT 04 Nov. This is the second X-flare within the last 6 hours.
An R3 radio blackout affected the Pacific Ocean region.
The Owens Valley Solar Array is recording substantial radio noise upto ~6 GHz. GPS users may notice poor signal stability.

A strong geomagnetic sub-storm is now in progress.
The Kiruna magnetometer just reached K7.
There's a slight change that Aurora may be possible over Scotland, Northern England, Northern Ireland and other high latitude locations.
