[1]Leonis Minorids [sic][1][2] (formerly Leo Minorids,[3] IMO designation: LMI; IAU shower number: 22) is a weak meteor shower that takes place from October 19 till October 27 each year, peaking on October 23.[4] With a weak moon the meteor shower may be visible with the naked eye, however this meteor shower is best observed only from the Northern Hemisphere with telescopic plotting.[5] This meteor shower is linked to comet C/1739 K1 and radiates from the constellation Leo Minor, which is a faint constellation north of Leo.[6] The meteor shower often only produces 2 meteors an hour.[7] The meteors usually pass at an average speed of 62 kilometers per second.
