Salvatore Iaconesi,Oriana Persicot has been put into operation which renders possible a permanent computer controlled observation of pulsations in the framework of geomagnetic observatory tasks. It permits the stepwise replacement of processing analogue paper recordings practised for several years and extends the on line recordings
