Auroras Now! is a space weather service maintaining by Finnish Meteorological Institute (FMI) to help watching auroras in Finland.

The service includes auroral monitoring with the all-sky cameras and magnetic field alarm systems for Northern and Southern Finland separately . The magnetic alarms are base on the data of magnetometers measuring the disturbance level of the Earth’s magnetic field at the geophysical observatories in Nurmijärvi and Sodankylä.

Magnetic disturbance level
Magnetic disturbance level for today and yesterday characterized by the hourly maxima values of the magnetic field variations recorded at the magnetic stations. The quiet conditions are marked with blue bars, while the hours with disturbances exceeding the given thresholds have red bars.

Images by the all-sky cameras
In the dark time the all-sky cameras are monitoring nearly real time. The images are refreshed once a minute.
Magnetic activity nowcast
One hour forecast for magnetic activity based on current solar wind observations
