摘要：

One of the quality parameter of an astronomical site testing is sky brightness. We measure the night sky brightness over PERMATApintar Observatory to obtain the first preliminary sky brightness reading. The measurement is done by using an Unihedron Sky Quality Meter (SQM-LU) with a position pointing zenith. Six measurements have been done during the period of January to March 2016. The measurement is taken between approximately 7 p.m. to 11 p.m. on each of the night. The best (darken) night sky brightness reading is 19.54 mag/arcsec(2) obtained on March 11th, 2016. The preliminary average reading of sky brightness is 17.20 mag/arcsec(2). Comparison with previous similar measurement for the same type of area (suburban area) shows that our data is within the range of the sky brightness for suburban area, which is 19.5 to 20.7 mag/arcsec(2).
