| Abstract: | For continuous acquisition and primary processing of short periodic geomagnetic variations at the Adolf Schmidt Observatory Niemegk recording equipment 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 with the process control computer system PRS 4000 carried out up to now on the monthly 3 World Days only. In addition to routine characterization of pulsation activity, especially by use of process control computers for on line primary processing extended investigations on the microstructure of diurnal variations of pc pulsation amplitudes in medium latitudes became possible. Now, these investigations can be significantly enlarged in a permanent observation with problem oriented on line data condensation. |
