Dwarf Planet 1 Ceres brightness

The current visual magnitude of Dwarf Planet 1 Ceres is 9.17.


The following chart is the predicted light curve (visual magnitude as a function of time) of Dwarf Planet 1 Ceres, 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.

Dwarf Planet 1 Ceres rise and set times

Location: Greenwich, United Kingdom [change]
Latitude: 51° 28’ 47” N
Longitude: 0° 00’ 00” E
Timezone: Europe/London

Today's Dwarf Planet 1 Ceres rise, transit and set times from Greenwich, United Kingdom [change] are the following (all times relative to the local timezone Europe/London):

Azimuth: 116.6°
Max altitude: 11.9°
Azimuth: 243.4°
Dwarf Planet 1 Ceres is above the horizon from Greenwich, United Kingdom

The rise and set times are defined as the time at which the upper limb of Dwarf Planet 1 Ceres 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.
