Relative Sunspot Number Observed from 2013 to 2015 at Langkawi National Observatory

摘要

LNO as compared to the international sunspot number, R_ISN. Errors fluctuate due to observations and analysis is carried out between 3 personnel that conduct the observations. Other contributing factor to these errors includes seeing condition andimage quality. We find that LNO k-coefficient (lease-square regression, R2 is 0.8045. Due to LNO’s solar observation consistency, it has recently been accepted as one of SIDC observing station network in June 2015 and one of two stations that use digital imageas the source of the relative sunspot number count reported daily.]]>
