(Moon rises at about h on June 4 in Singapore.) The Moon enters the Earth s umbra at h Singapore Standard (Local) Time. Mid-eclipse is at h. The Moon leaves the Earth s umbra at h. In other words, the umbral phase of the partial lunar eclipse will end 59 minutes after moonrise. The umbral magnitude (defined as the fraction on the Moon's diameter immersed in the Earth s umbra at maximum lunar eclipse) is The transit of Venus starts before sunrise on June 6. (Sun rises at about h on June 6 in Singapore.) Greatest transit of Venus is at h Singapore Standard (Local) Time. The transit visible from Singapore ends at h. The next transit of Venus will be in December Warning: Looking directly at the Sun without proper solar filter or protection would cause permanent blindness. You may view the Sun directly only through a special filter made for safe solar viewing. Never look directly through telescopes, binoculars or cameras towards the Sun without proper solar filters.

This penumbral eclipse begins at h Singapore Standard (Local) Time on Nov 28 5
6 as the Moon enters the Earth s penumbra. The penumbral eclipse ends at h on Nov 29 as the Moon leaves the Earth s penumbra. The penumbral magnitude of Shadow of the Earth in the penumbral region is not dark enough to cause a very obvious change in the illumination of the Moon. Hence penumbral eclipses are of only academic interest because they are subtle anard to be detected by the human eye.
