In summary: A Geomagnetic Storm alert has been released following a CME (Coronal Mass Ejection) caused by one or more of the flares over the last 24 hours. As with last time, those of you living in higher latitudes 45 deg North or South. Canada, nthrn USA, Alaska, nthrn Europe, Iceland, southern New Zealand and Tasmania - Australia. Keep an eye on the sky during your dark hours.In summary, a solar storm is coming and those living in higher latitudes should be prepared.

A SOLAR STORM IS COMING: Yesterday during a flurry of M-class eruptions, sunspot AR2673 hurled a CME toward Earth. NOAA forecasters say the cloud is likely to arrive late on Sept. 6th, causing moderately-strong G2-class geomagnetic storms with isolated periods of strong G3-class storming on Sept. 6th and 7th.

get you cameras ready people !
it's been a long time since we have seen a major to severe storm warning

SWS GEOMAGNETIC DISTURBANCE WARNING 17/42
ISSUED AT 0108UT/06 SEPTEMBER 2017
BY THE AUSTRALIAN SPACE FORECAST CENTRE.

Expect an increase in geomagnetic activity to Active to Major
Storm conditions with possible cases of Severe Storm conditions
at higher latitudes. Active to Major Storm conditions for 7 September
due to continuing CME effects which will gradually decrease over
8 September.

INCREASED GEOMAGNETIC ACTIVITY EXPECTED
DUE TO CORONAL MASS EJECTION
FROM 06-08 SEPTEMBER 2017
_____________________________________________________________

GEOMAGNETIC ACTIVITY FORECAST
06 Sep: Active to Major Storm
07 Sep: Active to Major Storm
08 Sep: Active

GEOMAGNETIC STORMS POSSIBLE TONIGHT: The first of two CMEs en route to Earth has arrived. First contact occurred on Sept. 6th at approximately 23:45 UT. NOAA forecasters say that moderately-strong G2-class geomagnetic storms with isolated periods of even stronger G3-class storming are possible in the hours ahead as Earth moves through the CME's magnetized wake.

+ I wonder what this (new fresh huge CME) will bring ... 3 days from now or so ... :

approx saturday
CME speed will be quite substantial ... probably 750 - 900 km/secD

It looks like yesterday's (Sept. 10) last X-class flare [X8.2] (of group 2673 - now rotated over limb), although close to limb produced a halo CME (i.e. with earth directed component), due to arrive around 12 Sept. (i.e. tomorrow). Does this mean more aurora activity from 2673?

1. When will the Aurora Alert be active for 6th and 7th Sept?

The Aurora Alert will be active starting on the evening of September 6th and will continue through the night of September 7th.

2. What is an Aurora Alert?

An Aurora Alert is a notification system used to inform people of potential sightings of the Aurora Borealis (Northern Lights). It is typically issued when there is a high chance of the Aurora being visible in a particular location.

3. How is the Aurora Alert determined?

The Aurora Alert is determined by monitoring solar activity, specifically solar flares and coronal mass ejections (CMEs), which can trigger the appearance of the Aurora. When these events occur, scientists can predict the potential for a visible Aurora and issue an alert.

4. Where is the best place to view the Aurora during the alert?

The best place to view the Aurora during the alert will be in areas with clear, dark skies and minimal light pollution. This could include remote locations, national parks, or high altitude areas. It is also recommended to check local weather conditions and Aurora forecasts to increase your chances of seeing the Aurora.

5. Are there any safety precautions to take during the Aurora Alert?

There are no specific safety precautions to take during the Aurora Alert, but it is always important to dress warmly and protect yourself from the cold weather. Additionally, if you are planning to view the Aurora in a remote area, make sure to inform someone of your plans and location. It is also important to never look directly at the sun during the alert, as solar flares and CMEs can also cause potential harm to the eyes.
