Hourly cosmic ray variations and their longitude and pitch angle distribution

Continuous ground level observations of cosmic rays give a chance to reveal the precursors of large interplanetary disturbances and geomagnetic storms. The picture of CR variations distributed by the asymptotic longitudes shows the characteristics features evidencing about an approach of interplanetary disturbance. These distributions can be pictured and studied using the ring station method which is realized in real time mode in the frame of e-Infrastructures project NMD in the Seventh Framework Programme. The Internet project is created for monitoring of such events
