Comet Tsuchinshan-ATLAS can still be seen tonight, but you may need some binoculars because it's no longer a bright, naked-eye object in the post-sunset sky.

Do you know where to look? See my sky charts below -- and my "cosmic coat hanger" technique for two different ways of locating comet A3 (also called C/2023 A3).

Now in the constellation Ophiuchus, the comet is slowing down in its apparent motion across the sky; expect it to simply fade and shrink over the next few nights.

The comet's coma measures around 130,000 miles (209,000 kilometers) in diameter, with a tail extending 18 million miles (29 million kilometers), but it's getting fainter and smaller as it heads off into the outer solar system -- probably never to return.

However, it remains a relatively bright, deep sky object visible well into darkness. To make things a little easier, there's now no interference from the waning Hunter's Supermoon.

It's a good idea to avoid light-polluted night skies if you want to see the comet. Check a light-pollution map or find a Dark Sky Place to observe from.

Although its magnitude of +2.8 makes it technically visible in a dark sky, you'll almost certainly require binoculars or a small telescope to see it. An alternative is to photograph the comet with a camera or a smartphone; a long exposure image helps it show up more easily.

Note: times and viewing instructions are for observers at mid-latitudes in the Northern Hemisphere. Check the exact time of sunset where you are and the comet's setting times on Stellarium Web for times that are accurate for your exact location.

Comet's distance from the sun: 73 million miles (118 million kilometers)

Comet's distance from Earth: 68 million miles (110 million kilometers)

At magnitude +2.8, the comet is technically within naked-eye visibility -- though you will need dark skies.

Wherever you observe from, there are two easy ways to find the comet this week. The first uses Venus and Arcturus -- two bright points of light close to the western horizon after sunset. The second (for those who don't have a clear view low to the western horizon) is to use bright star vega much higher in the sky. Both use my cosmic coat-hanger technique to locate the comet.

If you can see Venus and the bright star Arcturus close to the western horizon, make them the endpoints of a coat-hanger shape -- the comet will be the hook above them.

If you can't see one of these (since they are relatively low on the horizon), instead use bright star Vega above due west. Draw an imaginary line straight to the horizon from Vega and make a coat-hangar shape on the left -- the comet will be the hook to the side. Scan with a pair of binoculars until you find it.
