The Sun Sky Charts and Coordinates

This is a simplified sky chart, showing where The Sun is now with respect to the brightest stars and constellations.

More advanced sky charts are available on TheSkyLive for this object: 1) the Online Planetarium which is interactive and allows to select dates and additional objects to visualize; and 2) the Live Position and Data Tracker which provides the highest precision position data and features deep sky imagery from the Digitized Sky Survey.

The Sun Rise and Set Times

Today's The Sun rise, transit and set times from Greenwich, United Kingdom [change]. All times are relative to the Europe/London timezone.

The rise and set times are defined as the time at which the upper limb of The Sun touches the horizon, consideting the effect of the atmospheric refraction. As the atmoshpere conditions cannot be modeled precisely the times reported here should be considered correct with an approximation of few minutes.

Azimuth: 108.4°
Max altitude: 20.1°
Azimuth: 251.5°

Distance of The Sun from Earth

The following chart shows the distance of The Sun from Earth as a function of time. Distance data is measured in Astronomical Units and sampled with a 2 days interval.

The reported distances might be inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of Sun is also available as a real time updated value in the Live Position and Data Tracker.

Light Curve of The Sun

The following chart is the predicted light curve (visual magnitude as a function of time) of The Sun, according to the most recent ephemerides data. Magnitude data is sampled with a 2 days interval and there might be inaccuracies for objects changing brightness very rapidly during the course of a few days. For comets there could be large discrepancies between the observed and predicted brightness because of their highly dynamic behaviour.
