Ursids Meteor Shower (Peak Time and Date)

Ursids is a last major meteor shower in a year. An outburst was sometimes presented. In 1945, the strong activity as ZHR110 was recorded. Radio Meteor Observation caught some activity every year. Maximum in both radio and visual observation is observed around λ=270°.6 – λ=270°.7.
