Taipei, June 2 (CNA) The best locations to witness the partial lunar eclipse on June 4 are central and southern Taiwan, as heavy clouds are expected in other areas due to the outer rim of a tropical storm, the Central Weather Bureau said Saturday.
The bureau said Tropical Storm Mawar's outer rim may bring unstable weather to northern and eastern Taiwan until June 5, but skywatchers in central and southern Taiwan have a good chance to observe the celestial event.
The eclipse will have started by the time the moon rises June 4 at 6:35 p.m., the bureau said, adding that the phenomenon in the eastern sky will end by 8:07 p.m.
A partial lunar eclipse occurs when the moon passes behind the earth, which blocks the sun's rays and therefore casts a shadow on the moon.
The next partial lunar eclipse is scheduled to take place April 26, 2013, when only about 2 percent of the moon's surface will be shaded, the bureau said.
On Saturday morning, tropical storm Mawar was located 810 kilometers south-southeast of Taiwan's southern tip, moving at 11 kilometers per hour in a north-northwesterly direction.
The bureau said the storm, packing sustained winds of 82 kph and gusts reaching 108 kph, is not likely to have a major impact on Taiwan.
