Details:
A musical note from our atmosphere.
Around 05.30 UTC or 06.30 local time magnetic and ground current pulsations on my instruments.
Approximately 2 hours long and with a period time of 2 minutes and 14 seconds. Continuous geomagnetic ULF pulsations in the range between Pc4 and Pc5.
For the first time this year and sometimes only once a year.It's great to see that our atmosphere can make this happen.This phenomenon can also be seen on other magnetometers for example from Abisco and Kiruna,roughly in the same place of the auroral oval.
