Abstract:

 

The unusually low amplitude anisotropic wave train events  (LAEs) in cosmic ray intensity using the ground-based Deep River  neutron monitor data has been studied during the period 1991--94.  It  has been observed that the phase of the diurnal anisotropy for  majority of the LAE events remains in the corotational direction.   However, for some of the LAE events the phase of the diurnal  anisotropy shifts towards earlier hours.  On the other hand, the  amplitude of the semi-diurnal anisotropy remains statistically the  same whereas, phase shift towards later hours; similar trend has also  been found in case of tri-diurnal anisotropy.  The interplanetary  magnetic field (IMF) and solar wind plasma (SWP) parameters during  these LAEs are also investigated.
