Favorevoli le condizioni climatiche, non troppo intensa la luce lunare (con falce calante) e massima visibilità proprio durante la notte: lo spettacolo delle Quadrantidi, le prime stelle cadenti del 2019, in scena tra il 3 e il 4 gennaio, s'annuncia promettente. Lo sciame sarà poi ben popolato, con una frequenza di meteore che andrà da 50 a 100 all'ora, massima attorno alle 3 del mattino.
Questi corpuscoli, a differenza di altri, non hanno come progenitrice una cometa, bensì l'asteroide 2003EH1, precisano gli esperti, il cui consiglio è inoltre di puntare occhi, cannocchiali e binocoli verso Oriente per ammirare anche l'allineamento dei pianeti.
