Various photographic searches confirmed the existence of a weak stream at $RA=90.6$$^\circ$, $DEC=15.7$$^\circ$ on November 27, with $v_{g}=43.7$km/s [@lind71]. The stream was named as $\xi$-Orionids (Xi-Orionids, $\omega-$Orionids), currently recognized as established meteor shower November Orionids (NOO) within the IAU Meteor Data Center (IAU MDC) catalogue [@oh89] and later by @lind99. Moreover, other photographic December Monocerotids were published [@oh89] and complex analysis of December Monocerotids and $\xi$-Orionids done by @lind90. Even some historical records of fireballs might confirm that December Monocerotids were active in past centuries [@fox85; @has99].

In [-@hind69], @hind69 published his telescopic meteor observation from Dec. 11, 1964 and assigned 5 meteors to the new stream called 11 Canis Minorids. @hind69 computed that these meteors have parabolic orbits and much higher inclinations (over 100$^\circ$). A year later, the author suggested a connection between the shower and comet C/1917 F1 Mellish [@hind70] and determined the activity during December 9-14. @kres74 revealed that 9 meteors that create the second component of the December Monocerotids might be 11 Canis Minorids activity within December 4-15. Their inclination was determined as $i=29.1$$^\circ$ and the perihelion distance as $q=0.092$, which is closer to the Sun compared to the nominal orbit of the comet C/1917
