Transit of mercury

9.5.2016 at 14.15 - Espoo (III)
Janne Sievinen, Emil Sievinen, Ursa (Helsinki)

The beginning of the passage of Mercury. The planet has already moved completely in front of the Sun. The weather is moderate, a little fog at times and some thermal vibration when shooting from the balcony.

Quiet aurora band

17.3.2013 at 20.45 - Espoo (II)
Emil Sievinen, Ursa (Helsinki)

For a day, I watched with excitement the readings of Nurmijärvi's magnetometer and hoped that the magnetic field disturbances would continue until dark. At eight o'clock in the evening, northern lights were visible from the window in the northern sky, although nothing was visible in the celestial cameras. From there, head to Oitta and take the camera with you. And yes it was worth it: bright northern lights and even blue were in the sky at the most active stage.
