Search for New Astronomical Site in Indonesia: III. Astronomical Seeing Condition in West Timor
Abstract: Global
meteorological study over Indonesia has identified that Nusa Tenggara Timur is
a good candidate for an astronomical site. West Timor, in the eastern region of
Nusa Tenggara Timur, is subsequently selected to be surveyed both for
topographical and sky quality. The latter is studied theoretically in term of
transmittance of tropical atmosphere. This work presents in situ measurement
undertaken for Kupang (longitude: 123° 34′ 4″ E, latitude: 10° 10′ 19″ S) to
derive the seeing values. The same procedure was also performed for Lembang,
West Java (longitude: 107° 36′ 58″ E, latitude: 6° 49′ 33″ S) in order to
quantitatively compare the proposing site to the established one. Our result
shows that Kupang has about 50% better seeing condition than that of
Lembang.
