A partial eclipse of the sun will be visible in Europe, North Africa and Central Asia, including Pakistan on Tuesday (today). The eclipse will be visible in Pakistan with 13 percent obscuration of the solar disk, a Pakistan Space and Upper Atmosphere Research Commission (SUPARCO) official said. The solar eclipse will begin at 11:40am and end at 4:01pm. The greatest eclipse will be at 1:51pm and the greatest magnitude will be 0.86. For north Africa and much of Europe, the event starts at sunrise, whereas in central Russia and north-west China, the spectacle occurs at sunset. North-east Sweden should get the best experience. At 0850 GMT, near the city of Skelleftea, the Moon will cover almost 90% of the Sun's diameter. Partial solar eclipses occur when the Sun and Moon do not quite align in the sky as viewed from Earth, and the deep shadow cast by the smaller body passing across the bigger one just misses the planet. Nonetheless, the phenomenon will result in a dip in light, depending on how big a chunk of the solar disc the Moon can obscure. This effect will vary from place to place and in time. Northern Algeria was the first location to witness the phenomenon at 0640 GMT. In European cities like London and Paris, the eclipse will already be underway as the Sun rises, with the Moon covering up almost 70% of our star by 0812 GMT in the British capital, and 65% of the solar disc by 0809 GMT in the French capital. The further east the event tracks, the closer it gets to local sunset. Central Russia, Kazakhstan, Mongolia and north-west China will all observe an eclipsed Sun dive over the horizon.
