The Transit of Venus on the Midnight Sun Observed from the Tromsø Region

Steinar Thorvaldsen

Tromsø, the largest city in Northern Norway, is almost 70 degrees north, and, as luck would have it, a fantastic Midnight Sun shone down from the clear blue arctic sky during the entire night of the June 2012 transit. It was like a dream come true for astronomers in the area! The weather was perfect in most parts of the Tromsø region, and the Norwegian national TV channel, NRK, got the front row for its marathon broadcast that lasted for more than seven hours. Several groups observed the night-long transit that started just after midnight and ended after 7 a.m. One group took the cable car just outside Tromsø city to 420 m above sea level on Fløya mountain, while another group observed from the top of the Auroral Observatory by the lake Prestvannet on Tromsø Island. Both groups had telescopes and cameras to stream video and pictures to the internet and to national TV broadcasts.
