PABD promotes astronomy, educates public, holds Solar Observation

Bandar Seri Begawan – The Astronomical Society of Brunei Darussalam organized a solar observation to promote astronomy and educate members of the public on Tuesday (11 September 2018) morning.

Astronomy enthusiasts gathered at the car park of the International Convention Centre in Berakas from 10 am to 1 p.m.  to view the Sun through solar filters. The event was the first time in Brunei being organized for the public that employed the use of a special Hydrogen Alpha-telescope, which makes solar prominences and flares observable.

What happens during a partial solar eclipse?

A perfect  alignment of the Earth-Moon-Sun bodies is required for a solar eclipse to occur. As seen from a location on Earth, a solar eclipse happens when the moon moves in front of the Sun thus block the Solar Disk. A simulation of the partial Solar Eclipse as seen from Brunei in the morning of March 9, 2016 is shown in the video above. Since we will only witness the partial obscuration of the sun by the moon, features that are normally visible during totality such as corona and darkening of the sky/surrounding will not be observable from Brunei.

2011 Aug 01 Large Sunspots Notice

Three sunspots of Solar Cycle 24 were captured without any filter at sunset from Seri Kenangan Beach, Tutong on August 01, 2011. (Canon EOS 400D Lens EF-S18-135mm f/3.5-5.6 IS Focal Length 135.0mm)

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.

Solar Halo May 2001

Explaination: A halo is a ring of light surrounding the Sun or moon. Most halos appear as bright white rings but in some instances, the dispersion of light as it passes through ice crystals can cause a halo to have some color. Halos form when light from the Sun or moon is refracted by columnar ice crystals associated with thin, high-level clouds (like cirrus or cirrostratus clouds). [More]

MESSAGE FROM THE PHOTOGRAPHER

From: <amir.b.abdul-latip@shell.com.bn>

Assalamualaikum,

 I stumbled upon your astronomy website by accident (thru an email
forwarded to me) and I thought you might like to see a picture of the
sun I took a few days ago. It was an amazing sight, many people saw it,
people in Bandar might have missed it because of overcast sky. I dont
know the scientific explanation for the phenomenon, but most people
said it signified the death of a Wali of important person, and Allah
lessened the strength of the sun’s rays by covering it with a gray disc.
