Clear sky in the morning, stars are dimly lighting pack ice and snowy mountains around Vagabond. Some shy northern lights are adding a little colour to the scenery. At midday, without fading the stars, a soft twilight is giving an impression of light for a couple of hours. In the afternoon, the moon is taking over. Like a floodlight, she is illuminating the setting until the next day. Vagabond's mast is showing its shadow on the snow and becomes moondial. After all, polar night is not often dark! It is sometimes darker at noon than at midnight, we are loosing sleep over it.
By definition, twilight is not the same for everyone. It is the light from the sun when down to 18° below the horizon for astronomers, 12° for sailors, 6° for earthmen. Different twilights are separating people on their ability to detect light. Here at 76°27’N latitude, at noon in the middle of the polar night, the sun reaches 9° below the horizon. Almost night for sailors, dark night for earthmen. But what a light! We are flirting with astronomers privileges.
If the sky is clear on Saturday 10 December, in the morning, we will watch a full moon eclipse.
