The infrared source known as Orion n was detected in 1980 with observationsmade with the 3.8-m United Kingdom Infrared Telescope. About two decades later,sensitive observations made with the Very Large Array revealed the presence ofa mJy double radio source apparently coincident in position with the infraredsource n. The radio source was assumed to be the counterpart of the infraredsource. However, over the years it has been concluded that the radio sourceshows large proper motions to the south while the infrared source n isstationary. Here we reanalyze the proper motions of the radio source addingboth older and newer VLA observations than previously used. We confirm theproper motions of the radio source that at present no longer coincidespositionally with the infrared source. The solution to this problem is, mostprobably, that the infrared source n and the radio source are not the sameobject: the infrared source is a stationary object in the region while theradio counterpart is moving as a result of the explosion that took place inthis region some 500 years ago and that expelled large amounts of molecular gasas well as several compact sources. Considering the paper where it was firstreported, we refer to this double radio source as Orion MR.  In addition, we use these new observations to fully confirm the large propermotions of the sources IRc23 and Zapata 11. Together with sources BN, I, OrionMR, and x, there are at least six compact sources that recede from a point incommon in Orion BN/KL. However, IRc23 is peculiar in that its ejection ageappears to be only $\sim$300 years. The relatively large number of sourcesrules out as a possible mechanism the classic three-body scenario since thenonly two escaping bodies are expected: a tight binary plus the third starinvolved in the encounter.
