Abstract
The effects of high-speed solar wind streams from low-latitude coronal holes and coronal mass ejections (CMEs) on cosmic ray intensity in 2007 are studied. The database on Forbush effects created at IZMIRAN, with cosmic ray density and anisotropy calculated by the Global Survey Method (GSM) on the basis of Neutron Monitor network data has been used. The behaviour of the mean characteristics by all the Forbush-effects in 2007 caused by coronal holes (interplanetary magnetic field intensity and solar wind velocity, 10 GV cosmic ray density and equatorial component of the cosmic ray anisotropy) is calculated by the epoch method. Features of the Forbush-effects caused by high-speed solar wind streams from low- latitude coronal holes and coronal mass ejections are described.
