Add to ORKGSwitching off the light for one hour is annual global event to celebrate the Earth Hour. At that time, there is also campaign to observe the night sky with minimal light pollution. Hence, during this event, it is important to measure the level of light pollution using the Sky Quality Meter (SQM) device that was directed to the zenith. The research is intended to obtain comparison of the night sky brightness (NSB) between reguler days (23th and 25th of March) and Earth Hour day (24th of March). The measurement was performed in Yogyakarta that is located in -7.798893 degree south and 110.364992 degree East using the SQM-LU device. The location is the city center where the artificial light comes from the building, advertising boards, city lig...
