Abstract
Understanding the cloud obscuration effect is crucial for Hilal (young moon crescent) sighting Hilal is the youngest moon in a lunar month that is sightable with naked eye. these sightings are important for the Islamic dates, especially for the month of Ramadan, shawwal and Zulhijjah of the Islamic calendar. Hilal is always observed on the Western horizon during and after local Sunset. Often, cloud cover obscures the Sun and the Moon as they set on the Western horizon. The cloud obscuration on the Western horizon was studied through the assessment of cloud classification (CLC) and cloud trends involving low and middle altitude cloud. This study was conducted at Sheikh Tahir Observatory Pantai Aceh, the official Hilal sighting site for the state of Penang. A remotely-accessed Raspberry Pi-controlled camera was utilized to obtain interval time-lapse photography to capture visible, real-time ground-base images for CLC and cloud trends on the Western horizon.
