Research Abstract

The aim of this research is to determine star formation rate by monitoring local core-collapse supernova rate. This aim can be achieved by taking full advantage of Ashra's unique capability. From fiscal year 2007, we deployed our detector units in the Ashra Mauna Loa site and developed data acquisition system and environment monitoring system. We started optical observation in 2008. As of the end of fiscal year 2009, accumulated observation time reached 2774 hours. As a summary of our observation, we achieved good weather rate of 93% and operation efficiency of 99%. This stable long term observation is mandatory for supernova search. As to supernova analysis, we developed limiting magnitude analysis at first since this is the basic of all optical analysis. Currently, we are working to develop supernova search system and sensitivity evaluation system.
