Follow the geomagnetic development in real time! (NB! Absolute values are shown in the graphs. The data is not yet processed and may contain man-made signals. Real values in processed data (latest processed data 2016-04-30 23:59:59). Solar quiet curves shows the normal or quiet state for the magnetic field when not disturbed by solar storms. The development of quiet curves from 1978 can be seen here: Quiet curves 1978-).
Black version of this page (according to some "aurora hunters" white background makes it difficult to see images (blinds) on the page when out in the field)
Updates last two years Updated by Mats Luspa 29 March 2016. Problem with the proton magnetometer that was installed 10 December 2015 has lead to that the old proton magnetometer is now reinstalled.
Updated by Mats Luspa 23 February 2016. "Pelardifferens" was measured to -80.5 nT.
Updated by Mats Luspa 25 January 2016. Hardware problems in Kiruna. Contact and cables exchanged for the magnetometer.
Updated by Mats Luspa 22 January 2016. Added graph for 3d plot magnetic field in Kiruna.
Updated by Mats Luspa 7 January 2016. Added graph for data from ACE magnetometer where data is prepared by noaa.gov.
Updated by Mats Luspa 10 December 2015. New proton magnetometer is again connected and makes total field measurements until further notice.
Updated by Mats Luspa 16 October 2015. The old proton magnetometer is again connected and makes total field measurements until further notice.
Updated by Mats Luspa 16 October 2015. Black version of magnetokegrams added: Black magnetokeogram.
Updated by Mats Luspa 12 October 2015. First absolute measurement with data from new proton magnetometer made. The new proton magnetometer now makes total field measurements until further notice.
Updated by Mats Luspa 1 October 2015. Test of new proton magnetometer (GSM-90 v7.0).
Updated by Mats Luspa 21 January 2015. Realtime magnetokeogram implemented.
Updated by Mats Luspa 25 December 2014. Added experimental 3D magnetogram.
