02:45 UTC .YELLOW ALERT.
Minor geomagnetic substorm in progress.
Northern Lights can in some cases be visible. It is very rare and sporadic, but possible. It will most likely be very fleeting and short.
It will require patience as well as good knowledge of reading and interpreting magnetometer data...
Go outside of Stockholm city limits, go north of the city. If certain atmospherical conditions will be met it will hopefully appear. If it does, it will be low and faint (even to you a DSLR) on the horizon, approximately 0° to 5° (ich) from the horizon.
