Abstract

Abstract:
The spatial observability of the moon phases for different time and places in the world is
shown using chaotic time series prediction with fuzzy system. The results are compared
with a study using system thinking approach, which show a coincident of both results.
Recommendations are proposed for future study to compensate for the moon spatial
observability by using spatial state observer. Based on the analogy between moon and
sun, using system thinking approach, a proposal is introduced for further study to unify
the start of the moon phases.
