Observers using binoculars or a telescope should set their sights on Comet 21P/Giacobini-Zinner. This solar system traveler is making its second-best appearance since its discovery in 1900.
Comet Giacobini-Zinner is a relatively small comet just over a mile (2 km) in diameter.
The comet currently glows at 7th magnitude against the backdrop of Auriga the Charioteer, a region that rises in the evening and climbs high before dawn. Giacobini-Zinner lies within 2° of magnitude 0.1 Capella this morning.
The comet was similarly close yesterday morning, and remains a good target this week.
