Asteroid 249516 Aretha brightness

The current visual magnitude of Asteroid 249516 Aretha is 21.55.


The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 249516 Aretha, 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.

Asteroid 249516 Aretha rise and set times

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

Today's Asteroid 249516 Aretha rise, transit and set times from Greenwich, United Kingdom [change] are the following (all times relative to the local timezone Europe/London):

Azimuth: 110.7°
Max altitude: 17.9°
Azimuth: 249.4°

The rise and set times are defined as the time at which the upper limb of Asteroid 249516 Aretha touches the horizon, considering the effect of the atmospheric refraction. As the atmospheric conditions cannot be modeled precisely the times reported here should be considered correct with an approximation of few minutes.
