Abstract
We have correlated intensity decreases in the galactic component of cosmic rays observed at the Earth with solar phenomena. We have found that there exist intensity decreases detected underground, which are probably associated with long-lived interplanetary streams and which are not directly associated with single flares. We expect to detect the streams with underground monitors before the arrival of the streams at the Earth. The early detection will be in the northern or in the southern hemisphere, depending on the sign of the interplanetary field.
