Abstract

The Sun's shadow generated by multi-TeV cosmic-ray particles has been continuously observed with the Tibet-III air shower array in 2000 through 2004 during the active period of the Solar Cycle 23 except for winter seasons (Nov. - Feb.) when the Sun moves along the low elevation tracks. According to many observations of the activity, especially clear in the sunspot number, the Solar Cycle 23 has a dip called Gnevyshev Gap early in 2001. In the yearly variation of the Sun's shadow, it becomes faint with increasing solar activity and becomes deep with declining activity. We observed unexpected deepening of the Sun's shadow just in the year 2001 when Gnevyshev Gap appeared.
