Template:Short description Script error: No such module "Solar eclipse". A partial solar eclipse occurred at the Moon's ascending node of orbit on Monday, April 19, 2004,[1][2][3] with a magnitude of 0.7367. 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 eclipse was largely visible over the south Atlantic Ocean and north shores of Antarctica, most prominently the Antarctic Peninsula. The eclipse could also be seen in southern Africa at sunset. Considering the magnitude and the solar altitude, South Africa was the best place to observe this eclipse. In Cape Town, the Sun was about 40% obscured, while in Pretoria the Sun was 29% obscured. Further north, the eclipse remained visible up to Angola, the southern Democratic Republic of the Congo and Tanzania.

Eclipse season

Script error: No such module "Labelled list hatnote". 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.
