Resumen

Comet Iwamoto was discovered by Masayuki Iwamoto on december 20, 2018. This comet has an orbital period of 1,371.3 years [1], and its next passage around the sun will occur in the year 3390. The comet was closer to the earth on February 12 and its distance to our planet was 45 million kilometers. The perihelion occurred on February 7 [2]. The comet reaches aphelion far beyond the Kuiper Belt in the world of Severe Trans-Neptunian Things [3]. This comet is traveling at a speed of 238,099 km/h, relative to Earth [4]. From our Observatory, located in Pasto-Colombia, I captured several pictures, videos and astrometry data during several days. The animations were published by SPACEWEATHER on the following dates: February 14 [5] and February 23 [6]. The pictures of the asteroid were captured with the following equipment: CGE PRO 1400 CELESTRON (f/11 Schmidt-Cassegrain Telescope) and STL-1001 SBIG camera. Astrometry was carried out, and we calculated the orbital elements. We obtained the following orbital parameters: eccentricity = 0.9920 ± 0.0148, orbital inclination = 160.405 ± 0.031 deg, longitude of the ascending node = 147.484 ± 0.011 deg, argument of perihelion = 358.06 ± 0.06 deg, perihelion distance = 1.287039 ± 0.000636 A.U, mean motion = 0.00048 ± 0.00134 deg/d, absolute magnitude = 12.2. The parameters were calculated based on 77 observations (Feb. 14-23) with mean residual = 0.19 arcseconds. I also obtained the light curve of the body with our data.
