The night, hour by hour
The sky over Sydney from sunset to sunrise, on the town's own clock: the band shades from twilight to full dark and back, and each bar is when the Moon or a planet is above the horizon, drawn bright while it can be seen. The dot is the best moment to look.
Planets tonight
Where and when to look for each planet from Sydney. A planet counts as visible when it is at least 5° up once civil twilight is over; Uranus and Neptune need 10° and a darker sky, and binoculars or a telescope.

ISS passes over Sydney
The International Space Station crosses the sky as a bright, steady point, faster than a plane and without blinking lights. These are its visible passes over Sydney in the next five days, worked out in your browser from its latest orbit.

We email you on the day of each good pass over Sydney, with the time and where to look. Free, and you can stop it any time.
The station's live position, its orbit and every pass on a 3D Earth are on where is the ISS.
Southern lights from Sydney
On NOAA's rule of thumb it takes Kp 8.9 (G4) to bring the southern lights low over Sydney's southern horizon, and even the strongest storm on the scale does not bring it overhead. On NOAA's scale storms that strong come about 60 days per 11-year cycle. The camera on a phone picks up more than the eye.
The live forecast and the best time to look are on the aurora page for this region.
The next two weeks
Each night's sunset, its fully dark hours and the Moon. The last column is the darkness with the Moon down, the time for faint stars and the Milky Way; the best nights are marked.
