Asteroid (NEO) 2020 UG brightness

The current visual magnitude of Asteroid (NEO) 2020 UG is 19.42.


The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid (NEO) 2020 UG, 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 (NEO) 2020 UG rise and set times

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

Asteroid (NEO) 2020 UG is circumpolar and transits at 21:40 UTC (altitude: 82.6°)

The rise and set times are defined as the time at which the upper limb of Asteroid (NEO) 2020 UG 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.
