Update April 12, 2015: Another change to view a celestial conjunction of Venus and Pleiades today. Clear sky!
The brilliance of Venus and a beautiful set of “Seven Sisters” star cluster (the Pleiades) are visible very close to each other from Pantai Seri Kenangan, Tutong, at dusk today.

Satu ‘hunting’ milkyway telah pun dibuat dan dilaksanakan oleh saya serta rakan-rakan fotografer dari ‘Brunei Landscapiers’ seawal jam 0100Hrs. Alhamdulillah, cuaca yang berawan pada mulanya kian beransur cerah dan menampakkan keindahan jutaan bintang atau galaksi ciptaanNya…

To use the accompanying map, turn it around until it matches the view in your binoculars. Start your tour by learning the Moon’s large, dark plains, called maria (the Latin plural of mare, “sea”). Early telescope users and mapmakers in the 17th century thought these dark markings were similar to Earth’s bodies of water and gave them fanciful names like Mare Nectaris, “Sea of Nectar,” and Mare Nubium, “Sea of Clouds.” Today we know that the Moon is an airless, waterless, and lifeless world. The maria are in fact great lava flows that filled much of the lunar lowlands billions of years ago.
When the Moon is a slender crescent in the western sky after dusk, we see the features near the right-hand edge of the map. As you can see, Mare Crisium and Mare Fecunditatis are the only major “seas” visible. In the next few days the retreating terminator gradually unveils Mare Nectaris, Mare Tranquillitatis, and Mare Serenitatis. At first-quarter phase we see the entire right half of the map. After first quarter Mare Imbrium and Mare Nubium appear, and just before full, Oceanus Procellarum and Mare Humorum come into view.
At full phase the Moon is at its dazzling brightest. Because the Sun shines onto the Moon from almost directly behind us at this time, we see no shadows of craters and mountains. The bright ray system of the craters Tycho, Copernicus, and Kepler stand out especially prominently. The rays are splash patterns of debris from the impacts that formed the craters. After full phase the advancing terminator covers up the surface in the same right-to-left order.
Unlike astronomical telescopes, which give inverted (upside-down) and sometimes mirror-reversed images, binoculars show you right-side-up views that are never mirror-reversed, making comparison with the lunar map very easy. Once the map is oriented properly, you will be able to readily identify the major seas, craters, mountain ranges, and other features. In time the geography of this alien world will become as familiar to you as that of our own.
Present at the observation were Pengiran Shahdani (Vice President II), Awang Hj Mohamad Azri (Exco) and 4 other members.
The result of the observation was submitted to Islamic Crescents’ Observation Project (ICOP). See worldwide observation result here.
Assigned vantage points throughout the country could sight the new moon of Syawal 1432 H. The official announcement of the sighting was also made on TV and Radio and Brunei Darussalam starts Aidilfitri tommorrow, 31 August 2011.
Bandar Seri Begawan – The current sun is increasingly active with larger sunspots and the number increasing. Local solar observers are encourage to look at these sunspots safely with solar filters within this few days (Warning: Do NOT look at the sun directly).
As it can be seen from the photograph below, the sunspots appeared dark but in fact they are not. They were just appear dark by contrast. These regions can reach between 1100 to 2500 degrees Celcius and cooler than the surrounding surface.
These spots were capable of producing X-class solar flares which can effectively damage the man-made communication satellites but also interestingly producing green auroras around the Earth’s poles.
