The moon is back, first quarter, superb. Like the sun, hidden for about 4 months per year (length of the polar night at 78 degrees North), the moon disappear under the horizon for 9 days every 28 days cycle. Deep silence yesterday night, you could hear your heart. But cold is gone again, and the thin ice is not much resisting to the small passing lows. This morning, I can hear the waves at about 200 m from Vagabond, scientific work could well be delayed.
