The Solar Longitude (Abbrev: S.L., λ ☉) is 257 degrees, this value is the the date of maximum activity. It is measured as a degree with zero degree indicating spring equinox (roughly March 21st/22nd). 90 is the Summer Solstice, 180 is the Autumn Equinox and 270 is the Winter Solstice. This degree is independent of the calender. AMS .
The closest star to the radiant point of the meteor shower is Zeta Monocerotis. The coordinates can also be determined by the Right Ascension (100) and the Declination (8).
The Zenith Hourly Rate or how many you expect to see during the hour is 2. The ZHR can radically increase if the comet or associated object is close by. The speed/velocity of the Meteor Shower particles is 42 km/s. The population index of the meteor shower is 3. The population index refers to the magnitude distribution of the meteorites, the smaller the index, the brighter the meteors are, the higher, the dimmer the meteors are. For this particular meteor shower, bright meteors are more frequent.
The Monocerotids should be an easy meteor shower to spot due to it being close to Orion. Orion is probably the easiest constellation of all to see. In the northern hemisphere, the Monoceros constellation is to the east of Betelgeuse.
The Monocerotids appear about 7 p.m. in the evening but if you can wait until a little latter then it will be clearer for you to see. They should be visible for the rest of the night.
The Monocerotids are not as easy to spot in the Southern Hemisphere as they are in the north. You would need to wait until after 9.pm. to see them due to it still being light. Look in a easterly direction directly below the belt of Orion to be able to stand a chance to see them.
