Grahan, called as eclipse, is called the process when any celestial object is covered by another object, fully or partially. In other words, when the shadow of one celestial object covers the another celestial object. In terms of astronomy, when three celestial bodies; Sun, Moon and Earth get positioned in a straight line; and either Moon or Earth comes in the path of rest of the two, this astronomical event called Grahan occurs. Grahan or eclipse are of two types:
| Eclipse Date | Type Of Eclipse | Visibility in India | Places where Grahan will be visible | Time(IST) |
| 26th February, 2017 | Surya Grahan | No | South Africa, South America, Antarctica, South Atlantic ocean, Southern pacific ocean | 17:39 to 23:04 |
| 21st August, 2017 | Surya Grahan | No | Northern Pacific region, Antarctica, South Africa | 21:16 to 02:34 |
