Various other conjunctions of the moon with stars are marked 

 with aster iscs in the Nautical Almanac ; but they either happen 

 when the sun is above the horizon, rendering the occultations of the 

 smaller stars invisible, or prove to be only appulses, as visible from 

 Greenwich. The following will be very near appulses.
