Like the COM, the DLM have similarly been recently redefined. This shower too is quite weak, but is probably long-lasting, though more coverage after the Quadrantid epoch in January would be valuable. The shower is primarily a northern hemisphere target, from where its radiant can be properly observed from ∼ 23h local time onwards. Almost first quarter Moon means dark skies will prevail for much of the second half of the northern midwinter maximum night.
