Multi-chord observation of stellar occultation by the near-Earth asteroid (3200) Phaethon on 2021 October 3 (UTC) with very high accuracy

This is the first time any multiple chord observations have been made for such a small asteroid. According to observational findings, the apparent cross-section of Phaethon at the time of the occultation could be estimated if you use an ellipse with a major diameter of 6. 12 mm and a minor diameter of 4. 07 kilometers, with a small diameter of 6. 12 u00b1 0. 07 km and a position angle of 117. 12 u00b05 0. 07 km and a minimum diameter of 0. 07 km at the time of the apparent cross-1. 200b1 0. 07 U00b1 ellipse of the ellipse ue u00b1 0. 07 km and ellipse u00b1 0. 07 u00b1 0. 07 u00b1 0. 07 km and u00b1 0. 07 u00b1 0. 07u00b1 0. 07u00b1 0. 07 km and u00b1 0. 07°u00b1 The instruments that were used for this research are commonly used by several amateur astronomers in Japan for occultation measurements and are not difficult to obtain. This paper details the procedure and findings of our investigations using a CMOS camera and a GPS module so that many people will participate in occultation observations in the future.
