Bandar Seri Begawan – A subtle darkened shading on the Moon was detected during the Penumbral Lunar Eclipse in the early hours from Brunei Darussalam on May 06, 2023.

The Moon dimmed slightly because it did not pass through the dark umbral shadow. These photos were taken during the mid-eclipse at 01:22 a.m., when the full moon was almost fully passed through the Earth’s penumbral shadow:

The phenomenon started at 11.13 pm on May 05, 2023, when the Full Moon entered a penumbral lunar eclipse and lasted for 258 minutes.

During this lunar eclipse, the moon will drop almost completely outside the Earth’s dark umbral shadow, and touch only the diffused shadow’s outer zone, known as the penumbra.

The dark shading during penumbral eclipse of the moon was much subtle and challenging to observe comparing to during partial or total lunar eclipse. Nevertheless, the Earth’s shadow casts on the moon can be noticeable especially on photographs.

This eclipse is most visible in the Eastern Hemisphere – eastern Africa, eastern Asia, Australia and southern New Zealand.

On October 29 this year, Brunei Darussalam will experience another lunar eclipse which will be a partial obscuration.

Bandar Seri Begawan – A penumbral lunar eclipse occurs from 1.45 am until 5.04 am from Brunei Darussalam on Saturday, June 6, 2020, corresponds to 14 Syawal 1441H. During this event, the full Moon crosses the penumbral shadow of the Earth and causing only slightly dimmed on the Moon.

Since no part of the moon enters Earth’s much darker umbra, expect on subtle darkening on the full moon during this type of eclipse and might be difficult to distinguish with the naked eyes. The greatest eclipse will occur at 3.24 am, when the moon is positioned deep into the penumbra.

Event	Time (Brunei, UTC+8)
Penumbral Eclipse begins	6 Jun, 01:45:51

Table: Phases of the June 6, 2020, Penumbral Lunar Eclipse

The best way to observe and detect the changes during the eclipse of the 6 June moon eclipse is to use a camera – take one image of the moon before and after the eclipse; and one at maximum eclipse.

Watch the live stream of the event from Mini Observatory in Kampong Keriam, Tutong, Brunei Darussalam via www.facebook.com/bruneiastronomy at 1.30 am until 5.15 am, June 6, 2020, subject to weather.

Penumbral Lunar Eclipse on January 11, 2020

Bandar Seri Begawan – A penumbral eclipse of the moon will take place on Saturday, January 11, 2020, at pre-dawn hours, from 1.09 a.m. until 5.11 a.m in Brunei Darussalam. The first eclipse of 2020 is also visible from the geographic regions of Europe, Africa, Asia and Australia.

There are three categories of lunar eclipse: total, partial and penumbral. In a penumbral lunar eclipse, only the faint or diffuse outer shadow of Earth (known as penumbra) falls on the moon’s face. This kind of lunar eclipse is much more subtle, and much more difficult to observe, than either a total or partial eclipse of the moon. There is never a dramatic darkening of the moon, as in when the Earth’s darkest shadow (umbra) moves over the Moon during a partial lunar eclipse.

At best, at mid-eclipse (3.10 am), very observant people or by taking photo of the full moon using a digital camera will notice a slight dark shading (90% dimmed) on the upper left side of moon’s face. Other skywatchers will view and notice nothing at all.

There will be another 3 penumbral lunar eclipses in 2020 on June 6, July 5 and November 30. Only 6^th June 2020 penumbral lunar eclipse will be visible next from Brunei Darussalam this year.
