No longer in forceH3 rocket launch - falling debris area in western North Pacific
H3 rocket launch with falling elements reported in the western North Pacific. Initial activity 19 Oct 19:47-19:51Z, then daily windows 19:47-19:51Z from 20 Oct to 06 Nov. A polygon of positions defines the danger area; mariners should avoid the area during the stated periods.
Keep clear of the defined area during the stated times and maintain a sharp lookout. Navigate well clear of the polygon while windows are in force.
Background
H3 is Japan's medium-to-large launch vehicle developed by JAXA and Mitsubishi Heavy Industries and is launched from Japan's southern launch range. Launches produce downrange falling stages and debris, so maritime danger areas are issued on planned ascent trajectories. The listed polygon lies downrange in the western North Pacific and is used to protect shipping during stage separation and re-entry phases.
