Quadrantids Meteor Showers (Peak time and Condition)

Quadrantids is one of the greatest meteor shwoers in a year. The maximum of solar longitude is at 283°.15 by IMO.
Radio Meteor Observation is also able to observe a strong activity every year. Since a strong activity is not longer, observable meteor echoes are less than annual year under bad condition such as low radiant elevation or below of horizon. Maximum peak in radio is also observed at 283°.15.
