Visibility II / V
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.
