There has been a solar storm raging over the last 2 days. Holes in the corona allow high speed plasma to escape the Sun and fly out to impact Earth – if the hole is facing Earthwards.
As usual it has been cloudy and wet in Northern Ireland but I managed to catch this last night. The almost full Moon has illuminated the foreground and clouds.
I have learnt recently about the importance of the histogram in night sky photography and am trying to “fill my histogram” and keep the peaks to the left to ensure a good exposure with lots of data – seems to be working.
Carrickhugh, Ballykelly, Co. Londonderry overlooking Lough Foyle.
Canon 5D mark 2 with Canon 24mm f/1.4 L lens. 4 second exposure at ISO 1600 and f/2.2.
Aurora parameters when taken: Kp = 4, IMF Total = 13.7 nT, 8.8 nT south. Local magnetometer reading: 115.7 nT
Although this isn’t a patch on some of the very beautiful images out there, I’m actually quite pleased with this.
Taken in Ballykelly at about 0042 hrs BST – there were no NLCs and I decided to turn the camera up to the zenith.
Its the best Milky Way that Ive ever taken – there is a standard way to do this to demonstrate the quality of your site – a 20 second exposure at ISO 3200 – I tried this once before in my back garden in the town of Limavady and ended up with an orange mess.
You can see the light pollution at the mid left from Limavady caught in a passing cloud.
Canon 5D II with 14mm f2.8L II lens, 20 second exposure at ISO 3200.
I would love to claim that the bright streak is a Perseid meteor – I did see one beautiful orange example tonight, streaking across the sky – but this is just a satellite – it is just too uniform unfortunately 😦
The satellite is SL 14 R/B – Russian.
Just a faint display tonight – the eye could only see a faint glow – the camera picked up some detail and structure.
Type 1 by eye, Type 2 by camera – I checked using an astronomy programme – the Sun was within the 6-16 degree “window” below the horizon to illuminate NLCs.
Type 2 – diffuse bands and Type 3a – short straight waves – blending into the reddish twilight.
Canon 5D mark 2 with 85mm f1.8 lens at ISO200 and f2.2, 4 second exposure.
Hoping that stopping down 1 or 2 f-stops and exposing long enough to keep the histogram roughly centred will help. Still waiting for that spectacular display however! Maybe some day!
