The Gamma Normids meteor shower takes place within the boundaries constellation of the Norma. The meteor showers occurs between Feb 25 - Mar 22 with the peak occuring on the Mar 13 every year The Solar Longitude, mistakenly known as Lambda Omicron is 352.7 degrees. This value sometimes expressed as S.L. or λ ☉ 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 Gamma Normids meteor Shower radiate from the Norma constellation, a small constellation that is seen in the southern hemisphere. The radiant point, the point where the Meteors radiate from is near the star known as Gamma Normae which is the brightest star in the constellation.
The coordinates can also be determined by the Right Ascension (250) and the Declination (-51.1).
The Zenith Hourly Rate or how many you expect to see during the hour is 4. The ZHR can radically increase if the comet or associated object is close by. The speed/velocity of the Meteor Shower particles is -56 km/s. The population index of the meteor shower is 2. 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, faint meteors are more frequent.
