Our primary purpose in this choice of destination was the hope of seeing aurores boréales, northern lights.
There is, of course, never any guaranty of a natural phenomenon occurring.
We visited a center to learn about it.
This was about 9:10 in the morning, not quite light out, as you can see. The warm and cosy part on the sign in the window tickled me. It was very informative, explaining how they are caused by emissions from the sun which are then attracted to the earth’s poles and deflected in the atmosphere. So one needs a good probability, no clouds, and no light pollution.
The first night of our stay we were in Reykjavik and it was raining on and off.
The second night, in a smaller town, we went outside around 9 in the evening to no avail.
The third night we tried again, spending about 1 1/2 -2 hours out in a field. The hotel had loaned us all blankets and headlights. I had brought along the tripod and as nothing more interesting seemed to be appearing, I took a photo of the other people taking photos. This was in full darkness, a 15 second exposure, 800ISO.
This person reminded us that they had said at the center that the camera is often better at picking up the lights than our unaided eyes and he was getting some faint green trails. So I took a photo at 10 seconds. It still looked pretty much like broad daylight even though it was fully dark.
Another shot. You can see the people who had given up heading back to the hotel.
There is a very faint wafting of green a little bit above the horizon that can be distinguished when the photo is enlarged.
The fourth night, it was snowing and the fifth night we were back in Reykjavik with 0 probability, even the tours were cancelled for that night.
So that is as close as we got to seeing the Northern Lights.
