The new Lunar (Hijric) month begins on the next day of sighting the new crescent at west after sunset i.e. during twilight at dusk. One major issue that has affected Islamic new moon visibility for many years is misdirected, excessive and obtrusive artificial light. The unwanted light is what we called as light pollution and it is unavoidable as well. Thus by determining the threshold of limiting magnitude will multiply chances of the visibility. However, there is no study on parameter of the limiting magnitude threshold is known. Nevertheless, since the visibility of Islamic new moon is really rely on the magnitude of the sky. Therefore, sky limiting magnitude measurement is very important in order to enhance Islamic new moon visibility. The objectives of this study are: 1) to determine the threshold of sky limiting magnitude for parameter set up; 2) to evaluate visibility of Islamic new moon associated with light pollution; and 3) to investigate other parameter that might contribute to limiting magnitude during Islamic new moon observations. In brief, this study implements observational methodology. The main important result of this study is to find out a vital parameter for Islamic new moon observations in order to increase its visibility. This study helps us to understand the phenomenon better about the threshold of sky limiting magnitude for Islamic new moon.
