A Navigational Warning has appeared that looks to be for an airborne launch on 13-14 June. It most likely is a Pegasus-XL launch with TacRL-2, a Responsive Launch demo by the Space Force (the alternative is Virgin Orbit's LauncherOne launch of amongst others Brik-II, but that is said to be scheduled for the last week of June). The line-up of the hazard areas indicates a ~98 degree polar (and likely sun-synchronous) orbit. 090844Z JUN 21 NAVAREA XII 257/21(18,83). EASTERN NORTH PACIFIC. CALIFORNIA. 1.
