Description
In analyzing the anisotropy of galactic cosmic rays below 1 TeV, graphs
with time as the horizontal axis frequently represent the cosmic ray
intensity variations. Therefore, the anisotropy is often misinterpreted
as a "temporal variation," even though essentially regarded as a
"spatial distribution."
This paper presents a high-resolution two-dimensional map of the
solar-time anisotropy using the GRAPES-3 large-area muon telescope at
Ooty, South India, which has an excellent capability of observing the
muon intensity in 169 subregions within a 45-degree zenith angle with a
temporal resolution of 4 minutes.
