When will the Ursid meteor shower peak tonight?
It's not going to be a great year for Ursid viewing despite the potential for an outburst. Since the peak lands on a full moon, it's worth noting that the Ursids are expected to send some meteors across the sky -- though, not as many as there will be at the height of the storm -- from December 17 through December 25. However, the Ursids have a sharp peak, meaning there are many more meteors on December 21-22 than in adjacent days.
The best time to get outside to catch the peak? Sometime between midnight Friday and sunrise on Saturday, according to a report by space.com. In other words, you have time to take a quick nap before you head out into the cold. Or maybe that time is better spent preparing a few flasks of hot toddies?
Where will the Ursid meteor shower be visible?
To get the best view of whatever is visible, you need to make like Snake Plissken and escape New York or wherever you are. Light pollution is the mortal enemy of quality stargazing, and in this case, you already have the bright full moon working against you. Getting as dark of a sky as possible will help you see more meteors, as will giving your eyes 20-30 minutes to adjust to the darkness. (Though, that's no small ask in the middle of December.)
As always, you'll need the sky to be clear in addition to being dark. Any sort of cloud cover will ruin your viewing experience. Also be sure to avoid areas where tall trees or structures will block your view of the sky. You want to be able to see as much of the sky as you possibly can.
Here are a few more tips from the folks at NASA's Jet Propulsion Laboratory: "It is winter so bundle up if you want to watch for meteors, as it is getting late in the year! Get to a dark spot, get comfortable, bring extra blankets to stay warm, and let your eyes adjust to the dark sky. A cozy lounge chair makes for a great seat, as does simply lying on your back on a blanket, eyes scanning the whole sky."
Where to look for the Ursids in the sky (map)
The radiant point (where the meteors appear to emanate from) is the constellation Ursa Minor, or the Little Dipper, in the northern sky. With any meteor shower, it's advantageous to locate the radiant, but you shouldn't look right at it. The meteors are moving away from the radiant, so you should look slightly away from that point.
