The Sun
Are There Sunspots Today?
Here is a recent image of the Sun's surface showing the current sunspot activity:
The Sun Position
The Sun is currently in the constellation of Cancer. The current Right Ascension is 08h 07m 27s and the Declination is +20° 12’ 40”.

The Sun Distance
The distance of The Sun from Earth is currently 151,990,761 kilometers, equivalent to 1.015995 Astronomical Units. Light takes 8 minutes and 26.9866 seconds to travel from The Sun and arrive to us.
The following chart shows the distance of The Sun from Earth as a function of time. In the chart the distance data is measured in Astronomical Units and sampled with an interval of 1 day.
The value of the reported distance might be somewhat inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of Sun from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest approach of The Sun to Earth
Between January 2013 and December 2100 the closest approach of The Sun to Earth happens on Sun Jan 5 2020 at a distance of 0.98324388 Astronomical Units, or 147,091,191 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
The Sun brightness
The current visual magnitude of The Sun is -26.71.
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.
The Sun rise and set times
Location: Greenwich, United Kingdom [change]
Latitude: 51° 28’ 47” N
Longitude: 0° 00’ 00” E
Timezone: Europe/London
Today's The Sun rise, transit and set times from Greenwich, United Kingdom [change] are the following (all times relative to the local timezone Europe/London):
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.
