The MIRSI hold/waypoint has been there for many years and is on the 236 degree radial from POL (Pole Hill) at 25 miles, which is also the 066 radial from WAL (Wallasey)at 17 miles. The hold is a standard racetrack pattern to the right with the proviso that you do not go more than 30 miles from POL on the outbound leg of the hold. The lowest holding level is 6000 feet or the equivalent flight level.In geographical terms I think it is overhead Wigan.
All STARS to Manchester from the south via Brecon ( a Mirsi 1a arrival)the west via Dublin ( a Mirsi 1b arrival) or the northwest via The Isle Of Man ( a Mirsi 1c arrival) all funnel through Wallasey and then on to 'Mirsi'. Tend to get held there about 20% of the time in my experience.
It is used for LPL inbounds as well.
