Abstract

Light pollution causes inability to clearly observe astronomical bodies at night due to anthropogenic light sources especially in urban areas. Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) Observatory is an astronomical observatory situated in the light polluted city of Metro Manila. Light pollution was quantified in the said observatory before and after the Taal volcano phreatic eruption, situated approximately 109 kilometers from PAGASA Observatory, through luminance using a Digital Single-Lens Reflex (DSLR) camera. The magnitude of the light pollution before and after the said eruption was 16.63 and 17.22 mag/arsec², respectively, an increase of 3.50%. Furthermore, it showed that the night sky in PAGASA Observatory is under "City Scale – Level 8" according to Bortle Dark Sky Scale.
