Abstract
Obscuration of the Sun by the Moon during total solar eclipse generates the
changing of the sky brightness. Sky Quality Meter (SQM) was employed to measure the sky
brightness during the 2016 total solar eclipse. The sky was still bright at the first contact time.
It is shown by the SQM value of zero. Approaching the second contact time, the SQM value is
rising up started at the value of 5.92 mpsas. The curvature profile of the SQM measurement value
is similar to the curvature profile of the SQM measurement at the dawn and dusk. However, the
flatness part of the curvature is much shorter than night time value of SQM. The maximum of
SQM measurement value is lower than the SQM measurement value during the night in Ternate.
It is 12.47 mpsas and happened at the maximum phase of the eclipse. It was confirmed by the
fact that at the time of totality, the sky close to the horizon was still bright. There is a
discrepancy between the predicted and actual second and third contact and maximum eclipse
time. By assigning the maximum of SQM measurement value as the reference value of maximum
eclipse time, the actual second and third time can be calculated. The shape of curvature between
the actual second and third contact time is symmetry.
