Kým aktuálne prichádzajú Ursidy (December 17-26 with a maximum around December 22), we are more interested in the January ones Kvadrantídy. Tento meteorický roj patrí medzi výdatné s predikovaným maximom 2.-4.januára 2021. Maximum býva však pomerne krátke.
ZHR by malo dosiahnuť 120 (45 až 200). Roj sa skladá prevažne z väčších častíc moving at a speed of 41.5 km/s.
