Sunset at 1827 local time

 

Tutong – April 19, 2015. Almost despaired by the weather as the western sky was partly cloudyย  whenย seeking theย young moonย at Bukit Agok this evening.ย ย The sun set behind theย real horizon of which very muchย assisting our telescope alignment and hadย given us hope indicating ย for a clear hazy patch in the sky.ย Sunspots were visibled through a 100mm f/6 refractor attached with a solar filter when the scope slewed at the sun.

Sunspots were observed at two different areas of the Sun.

After sunset, at 1827, the scope was pointed to the Moon revealingย its locationย which wasย behind thick clouds. However,ย there was some opening in clouds aboutย 1 to 3 degrees just nearlyย above the horizon,

At 1852 orย 25 minutes after local sunset, the scope was pointing to the cloudless area,ย very lowย ย in the westย horizon.ย  At that instance, theย super-thin youngย lunarย crescent of Rejab 1436H was firstlyย appeared through the telescope. Even so, with optical aid, ย the Hilalย (crescent) was hardly seen to the eyes as it was washed out by the twilight.ย Not until 4 minutes after that, the crescent was visible to the naked eyes through the viewfinder.

Theย new Moonย sightingย was conducted by Ustaz Saifulbahri and Hazarry of the Astronomical Society of Brunei Darussalam. Thisย afternoon’s sighthing was a newย record set for the youngest Moon with age of 15.8 hours old ย ever seen with optical aid in Brunei. Previous record was a 19 hours old observed in November 2004 (here).
