There will be a lunar eclipse (the moon in the earth's shadow) visible from Singapore early Wednesday morning, 5th May. Got the following info from singastro.org forum:
The total lunar eclipse will occur after midnight on May 5th with the following Singapore local times:
Penumbral Eclipse Begins: 1:50:53AM
Partial Eclipse Begins: 2:48:20AM
Total Eclipse Begins: 3:52:07AM
Greatest Eclipse: 4:30:16AM
Total Eclipse Ends: 5:08:27AM
Partial Eclipse Ends: 6:12:15AM
Penumbral Eclipse Ends: 7:09:36AM
At time of totality, the moon will be 21 degrees above the SWW horizon. So do make sure you have a clear view for this if you are observing or imaging the eclipse. For your information, the moon will set at 6:04AM so we will only be able to see the eclipse progress until just before partial eclipse ends.
If you are interested in photographing this astronomical occurence, take a look at this pdf done by the Astronomical Society of Australia. (Errr... only wish the Astronomical Society of Singapore had such info on their website.) The photography info is on page 4 and 5.
