End of Night
With the stiff competition from Arctic Organist – there you’ll find the “countdown to the midnight sun” – and coming to you further South, Yorkshire Viking Norway cannot hope to beat Arctic Organist on being first. The Arctic Organist will have the midnight sun three days before we do.
So Yorkshire Viking Norway is going new ways to be first! We will now tell you that from today there is no more night. This deserves some qualification, since the last twilight you can see tends to disappear at about quarter to nine (this of course will soon be a quarter to ten when we adjust the clocks tonight). However, scientifically speaking the darkest time of our day is no longer night. That is because the sun is never lower than 18° below the horizon. This means that astronomical twilight never ends.
For those of you who are scratching your heads, there are three types of twilight. The first is what you get immediately after the sun has set, or just before it rises. This is defined as being the time when the sun is below the horizon, but no lower than 6°. This is called civil twilight. In this time, it is usually possible to continue outdoor activities without the aid of artificial light. Then you have the second type of twilight, which is called nautical twilight, when the sun is somewhere between 6° and 12° below. This type of twilight is what I call the “blue”-type, and in this you do need the aid of artificial light to continue doing things outdoors. Lastly there is the twilight when the sun is lower than 12° but no lower that 18°. The sun’s illumination is almost imperceptible, and unless conditions are optimal you won’t see it at all. Even if you do, it will be no more than a very faint trace on the horizon.
So there really wasn’t so much to make then of today’s great happening – other than beating Arctic Organist to the goal. The next landmark in our Arctic year will be on the 13th April. From then on nautical twilight never ends, so perhaps that is the point at which you would notice that it never really gets dark any more (weather can of course still alter this). Finally, before Arctic Organist beats us by three days in getting the midnight sun on the 21st May, from the 2nd May there is nothing more than civil twilight. That is to say that, in practice, it is by then light all day even if it is cloudy as well.
In Lødingen, the midnight sun will be visible from the 24th May. Tonight, as pointed out above, we move the clocks an hour ahead for summer time. Remember to change yours before you go to bed!
