Asteroid (NEO) 2021 GT brightness

The current visual magnitude of Asteroid (NEO) 2021 GT is 40.81.


The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid (NEO) 2021 GT, 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) 2021 GT 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 (NEO) 2021 GT rise, transit and set times from Greenwich, United Kingdom [change] are the following (all times relative to the local timezone Europe/London):

Azimuth: 75.3°
Max altitude: 52.8°
Azimuth: 283.9°

The rise and set times are defined as the time at which the upper limb of Asteroid (NEO) 2021 GT 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.
