•Such potential studies can be used for better

NMSC/KMA during COVID-19 pandemic◆We are in KSEM long-term (>1year ) data review phase and,
fortunately the Sun is relatively calm these months, there is no big
change in regular KSEM operation.
◆ Work from/at Home▪ Since end of June 2020: Once in three days with rotation▪ Since end of November 2020: Once in four days with rotation▪ Maybe ‘Once in three days’ again soon after…

Summary◆We are okay and have no significant problem due to COVID-19
pandemic, at least until now.
