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

Today's Asteroid (NEO) 2018 BA3 rise, transit and set times from Greenwich, United Kingdom [change] are the following (all times relative to the local timezone Europe/London):

Azimuth: 104.0°
Max altitude: 24.5°
Azimuth: 256.0°
Asteroid (NEO) 2018 BA3 is above the horizon from Greenwich, United Kingdom

The rise and set times are defined as the time at which the upper limb of Asteroid (NEO) 2018 BA3 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.
