“…Brightness is a factor to consider while performing astronomical observations, as objects visible from Earth are impacted by their contrast with the sky's brightness. 27 The sky's brightness is determined by a number of elements, including the sun's altitude, integrated galactic light, integrated starlight inside the galaxy, zodiac light, night airflow, aurorae, and twilight emission lines. 28 On the Bortle Scale, sky brightness is categorised into nine categories: excellent dark-sky location, typical genuinely dark location, rural/suburban transition sky, suburban sky, brilliant suburban sky, suburban/urban transition sky, city sky, and innercity sky.…”

On May 26, 2021, the ITERA Lampung Astronomical Observatory (OAIL) got the opportunity to watch the Total Lunar Eclipse (TLE). The observations had two goals: determining the most efficient filter for observing the Penumbral Lunar Eclipse (PLE) and determining the influence of TLE phenomena on sky brightness. The acquired picture data is analyzed using the photometric approach. Six sample points are utilized to calculate the magnitude of the PLE. According to the findings, the blue filter is the generally ideal filter for detecting PLE. Tycho crater had the greatest magnitude of -18.1 while mare Imbrium had the highest magnitude 100 The Usage of UBVRI...

“…Since there was no study on sky limiting magnitude at site in Table 1, we hypothesized that light pollution really has impact on the crescent observation which is based on hilal observation report from 1972-2015 by JAKIM (Malaysia Department of Islamic Development), before 1990, the hilal was more frequently seen in 29th day. After 1990, the hilal was frequently seen in 30th day - Recent study showed Telok Kemang light pollution level has getting worsen due to artificial light [14]. One major issue that has affected hilal visibility for many years is misdirected, excessive and obtrusive artificial light.…”

Muslims has differentiated between new moon and Islamic new moon (hilal). The determination of first day of months based on visibility of Islamic new moon (hilal) i.e. sightings of the first sliver of the waxing moon marking the start of each month. One major issue that has affected hilal visibility for many years is misdirected, excessive and obtrusive artificial light. The objective of this research is to study the impact of light pollution on the visibility of hilal. The data were taken using Sky Quality Meter (SQM) which records the visual magnitudes per square arcsecond (mpsas) to measure sky limiting magnitude. Result showed that reading between 16-22 mpsas, the chances to witness hilal is high. Any lower than 16mpsas, the hilal is not visible. The main result of this research is to find out a vital parameter of hilal observations which leads to propose a new criterion i.e. sky limiting magnitude.
