AB  - The sky brightness measurements were
performed using sky quality meter as small size and
portable photometer with output directly in magnitudes
per arc second square (mass). Observation with 3 sec
temporal resolution was recorded at Depok city
(-6.392559 S, 106.761605 E) from March 15th to
December 16th 2017 but I select data with rules:
only 2 days after and before moon-sun conjunction and
sky brightness only in range with limitation astronomical
twilight after sunset to astronomical twilight before
sunrise. The data which I was collected are 21 days it
shows the range between 13.8-19.01 mass, the average is
15.11 mass with standard deviation 0.89 mass. According
Bortle scale, Depok city is in inner city or the 9th scale, so
in Depok city what can be seen only cllestial objects like
the moon, planets and some bright stars.
