The observed values of Magnitude, Coma Diameter and Tail Length are derived from the most recent observation recorded at the Comet Observers Database. The value of Predicted Magnitude comes from the JPL Horizons ephemerides service and, in the case of comets, might be inaccurate given the highly dynamic and unpredictable behavior of these objects. When available, please refer to the Observed Magnitude value and consider the Predicted Magnitude as a directional indication. We acknowledge with thanks the comet observations from the COBS Comet Observation Database contributed by observers worldwide and used in this table to report recent comet observations.
Today's rise, transit and set times of Comet 150P/LONEOS from Greenwich, United Kingdom (all times relative to the local timezone Europe/London):
- 150P/LONEOS is above the horizon from Greenwich, United Kingdom.
- Right now it is placed in the South-South-West direction at an altitude of 23° above the horizon.
- Given its current magnitude, 150P/LONEOS is visible only through long exposure photography.

Comet 150P/LONEOS Distance from Earth
The distance of Comet 150P/LONEOS from Earth is currently 204,727,591 kilometers, equivalent to 1.368519 Astronomical Units. Light takes 11 minutes and 22.8977 seconds to travel from Comet 150P/LONEOS and arrive to us.
The following chart shows the distance of Comet 150P/LONEOS from Earth as a function of time. In the chart the distance data is measured in Astronomical Units and sampled with an interval of 1 day.
The value of the reported distance might be somewhat inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of 150P/LONEOS from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Comet 150P/LONEOS to Earth
Between 1 January 2013 and 30 December 2100, the closest approach of Comet 150P/LONEOS to Earth happens on Wed Feb 14 2024 at a distance of 0.847468 Astronomical Units, or 126,779,437 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Comet 150P/LONEOS Brightness and Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Comet 150P/LONEOS, 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.
