Asteroid (NEO) 2020 WO brightness

The current visual magnitude of Asteroid (NEO) 2020 WO is 20.78.


The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid (NEO) 2020 WO, 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 WO 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 WO is circumpolar and transits at 20:48 UTC (altitude: 80.4°)

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