A solar eclipse occurs on a new moon day when the disc of the moon comes between the earth and the sun, partially or totally blocking the sun as seen from the earth for some time.

On April 30, a partial solar eclipse will be visible from the southern and south-western part of South America (Argentina, Uruguay, Chile and Bolivia), the Pacific and Atlantic oceans and most of Antarctica.

The solar eclipse as always starts at one location and because of the spinning earth, ends at another location. 

The partial eclipse will begin on that day around 6.45 (GMT). 

For India, it will be 12.15am on May 1. The maximum eclipse will take place around 2.11am (Indian time). The eclipse will end at 4.07am (Indian time).
