... The first total lunar eclipse of the new millennium visible from Northern Ireland will occur on the evening of Tuesday, 9 January. A total lunar eclipse results whenever the Moon passes completely into the shadow cast by the Earth. ... The partial phase of the eclipse will begin at 6:42 p.m. and end at 9:59 p.m. The total eclipse phase will last from 7:50 p.m. to 8:52 p.m. The next total lunar eclipse occurs on the 16th May 2003 when it is marginally visible just before dawn. ...
