From Leeming facebook:
The airfield will be open until around midnight until 26 May in order to provide operational training.
The Station will be hosting a multi-engine aircraft for night-flying activities. We understand our responsibility as good neighbours to inform the local community of such events that are additional to our normal flying activities and every effort will be made to keep the disturbance to a minimum.
