Buenos Aires is the marker on the globe — on the daylit half right now, riding the dotted circle its spot traces as the Earth turns. The moon is 165° from the sun in the sky now, and that angle is the phase: waxing gibbous. You are looking down on the Earth from far above its orbit, from the south — the side you are on — with sunlight arriving from the top left, so the half of the Earth facing that way is the half having its day. Sizes and distances are not to scale; the directions are.

That angle sets the tides, too. The moon does most of the pulling and the sun about half as much, so when the two line up — new moon and full moon — their pulls add and the tide runs to its biggest (spring tides); when they sit square on at the quarters the pulls fight and it runs to its smallest (neaps). The coast follows a day or two behind, and the shape of the shore matters as much as the sky does.

Also see moonrise, moonset & the phase in Buenos Aires, and the Sun, Earth & Moon movement simulator for Buenos Aires, to watch how the three move together over a day, a week or a month.

The moon is up too — 6.5° above the horizon in the east-southeast. Moonrise, moonset and tonight's phase →

The sun is well up. Altitude is how far above the horizon the sun sits; azimuth is the compass bearing to look along, measured clockwise from north. Shown for 5:46 PM; this updates to the live position when the page loads.

The three twilights are just how far the sun is below the horizon: civil to −6° (bright enough to read outside), nautical to −12° (the horizon is still visible at sea), astronomical to −18° (true darkness for stargazing). Golden hour is the warm, low-angle light photographers love, when the sun sits between −4° and +6°; blue hour is the deep-blue band just beyond it, from −6° to −4°. A dash means the sun never gets that low here on this date.

What time is sunrise in Buenos Aires, Argentina today?

The card above computes it live in your browser for today's date, using Buenos Aires's coordinates — along with sunset, solar noon, first light and last light, all in Buenos Aires's own time zone.

What are first light and last light?

Civil twilight — when the sun is less than 6° below the horizon. It's bright enough for most outdoor activities before sunrise and after sunset.

Why do the times change every day?

Earth's tilted axis means the sun's path moves through the seasons — days lengthen toward the summer solstice and shorten toward the winter solstice, so sunrise and sunset shift a little every day.
