Dec 23, 2014. DARK MOONLESS SKY TONIGHT and Comet Lovejoy C2014 was positioned high above our Brunei sky at around mid-night.
Recently in August this year, An Australian amateur astronomer, Terry Lovejoy, discovered his fifth comet, C/2014 Q2 (Lovejoy).
The photograph of the Comet was captured from Tutong, Brunei Darussalam last night. It appeared amazingly bright through a telescope and features a greenish coma with a faint tail.
Based on the image above and comparing the magnitudes of the background stars, the comet is currently at about magnitude +5.
At the moment, the comet is hardly visible to the naked eyes if you are in a small city with light pollution. Hence binoculars or a telescope is required to view it.
Reports from astronomy communities said that the comet is still brightening. The comet will be still viewable throughout January next year and it will be at maximum brightness by mid-January 2015.
