Solar eclipse of October 7, 1801

}}

A partial solar eclipse occurred at the Moon's descending node of orbit on Wednesday, October 7, 1801, with a magnitude of 0.3505. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.

The partial solar eclipse was visible for parts of modern-day New Zealand and Antarctica.{{cite web|title=Solar eclipse of October 7, 1801|url=http://eclipse.gsfc.nasa.gov/5MCSEmap/1801-1900/1801-10-07.gif|publisher=NASA|accessdate=June 15, 2012}}

Eclipse season

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight. The first and last eclipse in this sequence is separated by one synodic month.
