Photo exhibition in Tehran, Iran

These are truly exciting times! I still can’t quite believe it, but on April 8th, 2016 was the opening of the photography exhibition “Four Seasons in Finland” in Tehran, Iran. I’m very proud to be part of the exhibition alongside six other photographers from Finland. The exhibition is organised by the Embassy of Finland in Tehran and still ongoing until May 4th, 2016. The location is Tajrish Metro Station.

If you find yourself in Tehran, you know where to go 😉

When the darkness fades away

Between each day and night are three phases of twilight. The astronomical, nautical and – the brightest – civil twilight. Wait a minute, not every night. Ok, let me stop right there. That isn’t true for all places on our planet. Let’s take Oulu (surprise, surpise) for example, located at 65°N, summer nights are bright as daylight. The twilight phases I mentioned above become more and more important.

Astronomical twilight:
Being the darkest twilight zone, the sun is between 12° and 18° below the horizon. While faint stars and other objects are then tricky to observe, auroras are easily visible. The first day without proper night (pitch black that is) here in Oulu was actually yesterday, April 9th, 2015. Astronomical twilight is then the darkest phase for about two weeks.

Nautical twilight:
That’s when the sun is between 6° and 12° below. It is bright enough to see the horizon. Auroras are partly visible then; more exact: the sun needs to be around 10° below or lower. Going towards summer here in Oulu, on May 17th will be no more nautical twilight.

Civil twilight:
That’s right, the sun is then between 0° and 6° below. Outdoors it’s bright enough for almost anything, no point to talk auroras. In Oulu these are our brightest nights and we have about 73 of them.

Going further North, the nights will be brighter and brighter. Breaking through the Arctic Circle, the sun will be visible throughout the night – unless the horizon is covered by mountains, etc.

Ok, ok, enough with the numbers 🙂 If you are interested in your local twilights, head over to www.timeanddate.com , that’s what I did.

Last aurora season I caught the last ones on April 25th at 1.30am. As you can see with the bright skies towards North it was very very faint. This year I’ll problably sleep 🙂

G5+ geomagnetic storm predicted for June 20-22, 2015

A huge plasma cloud has errupted on the sun and it is now on its way to Earth. Due to the tremendous size it moves slowly and predictions are that it will reach Earth sometime around June 20-22, 2015. While the reason for this erruption is still unclear, aurora fans will have finally time to prepare and arrange travels well in time. First calculations tell, that curiously the brightest auroras can be observed during lunch time and not – as usually – during night time. Good luck to all of you!

As for you photo and real-time geeks, no problem with high ISO noise for that event 😉
