  The magnetic storm around 1859 September 2, caused by so-called Carrington
flare, was the most intense in the history of modern scientific observations,
and hence is considered to be the benchmark event for space weather. The
magnetic storm caused worldwide observations of auroras even at very low
latitudes such as Hawaii, Panama, or Santiago, and the available magnetic field
measurement at Bombay, India, showed two peaks: the main was the Carrington
event which occurred in day time in East Asia, and a second storm after the
Carrington event which occurred at night in East Asia. In this paper, we
present a result from surveys of aurora records in East Asia, which provides
new information of the aurora activity of this important event. We found some
new East Asian records of low latitude aurora observations caused by the storm
which occurred after the Carrington event. The size of the aurora belt of the
second peak of the Carrington magnetic storm was even wider than usual
low-latitude aurora events.
