Auroras Now! Is a service which helps watching auroras in Finland. Finnish Meteorological Institute (FMI) maintains the service, which includes magnetic field alarm systems for Northern and Southern Finland separately and an auroral monitor for Northern Finland. The magnetic alarms are based on the data of magnetometers measuring the disturbance level of the Earth’s magnetic field at the geophysical observatories in Nurmijärvi and Sodankylä. The auroral monitor shows images of the all-sky cameras. Auroras Now! is part of the ESA Space Weather Applications Pilot Project.

By clicking the thumbnail below (left) you can see the present magnetic disturbance level, as characterized by the hourly maxima values of the magnetic field variations recorded at the two observatories. The quiet conditions are marked with blue bars, while the hours with disturbances exceeding the above given thresholds have red bars.

During the dark hours the near real-time images by the all-sky cameras are presented (thumbnail on the right). The images are updated once per minute.
