Reykjanesviti is Iceland's oldest lighthouse. It serves as a landfall light for Reykjavík and Keflavík. The tower is a 31 metres (102 ft) tall construction, situated on the southwestern edge of the Reykjanes peninsula. The original structure was built in 1878; just eight years later the building was destroyed by an earthquake. In 1929 the current Reykjanesviti lighthouse, a concrete construction yet with traditional looks, was illuminated. Its focal plane measures 73 metres above sea level.
The light characteristic is "Fl (2) W 30 s.", i.e. a group of two flashing lights every 30 seconds. An antenna for the transmission of DGPS-signals in the longwave range is mounted on the rooftop. There is also a two-story keeper's residence built in the modern area, and the lighthouse has a resident keeper.
The bright dancing lights of the #aurora are actually collisions between electrically charged particles from the sun that enter the earth's atmosphere. The lights are seen above the magnetic poles of the northern and southern hemispheres. They are known as 'Aurora borealis' in the north and 'Aurora australis' in the south..
Auroral displays appear in many colours although pale green and pink are the most common. Shades of red, yellow, green, blue, and violet have been reported. The lights appear in many forms from patches or scattered clouds of light to streamers, arcs, rippling curtains or shooting rays that light up the sky with an eerie glow.
