It is strongly recommended that Target of Opportunity proposals (especially expected ToO) are submitted to regular CfP of KaVA. Unexpected or urgent ToO can be submitted to ask ‘Director’s time’ at any time. These proposals must include specific triggering criteria to initiate an observation. The ToO is valid for one year when it is approved. The proposals to Director's time must be submitted by PDF files using e-mail to kavaprop (at-mark) kasi.re.kr.
