It looks like the summer is back again, we have had some brilliant days here in the west, with more to come for the next few days! Unfortunetly the months are pushing on and the evenings are getting shorter.

Meanwhile a bit further away, on the Sun, there was a massive x-class CME on Wednesday afternoon which should be hitting Earth Friday night / Saturday. CME’s when they hit Earth are what cause’s the Aurora at the north and south poles. The larger the CME, the further away from the poles the Aurora or (“Northern Lights” as they are more commonly known) are visible. The Aurora should be visible as far south as Cork this weekend, if the sky is clear.

I have been trying to get a shot of the Aurora for the last 3 years as there have been numerous x-class flares recently. Unfortunatally every time there has either been too much cloud cover, fog or once on a clear night the moon was too bright! Hopefully I’ll have better luck this weekend.
