Star Party Sri Lanka

Star Party Sri Lanka, commonly known as Star Party, is an astronomical observation competition held in Sri Lanka since 2004, jointly organised by Ananda College, Colombo and Mahamaya Girls' College, Kandy. It is the longest-running inter-school astronomical observation competition in Sri Lanka. It happens annually at the University of Peradeniya premises typically in the first quarter of the year. However, in some years it was held in the other periods of the year due to various reasons. Star Party is considered the most important event in the Sri Lankan amateur astronomical calendar.
