unchanged by processes that have developed near the Sun. Galactic tides and the gravitational influence of nearby moving stars disrupt the faint orbits of these tiny objects, with some dropping off the Oort Cloud over thousands of years in a parabolic orbit toward the Sun. In its final approach to the interior of the Solar System, the gravity of the great planets can alter the orbits of comets enough to transform them into hyperbolic ones, leaving our system forever; or elliptical, causing their periodic return. After obtaining enough observations of comet C / 2019 Y4 (ATLAS), its orbit could be calculated, which due to its similarity has been determined to be a fragment of Great Comet C / 1844 Y1, which reached magnitude 2 and a tail of up to 15 degrees of

longitude observable with the naked eye in the evenings of the first days of January 1845. The fragmentation of the “father comet” could have happened 4,000 years ago, according to Honduras Phone Number List  the recalculated orbit of C / 1844 Y1. Since the beginning of 2020, interest in comet C / 2019 Y4 (ATLAS) increased as fast as its brightness increased, which by early March had already reached magnitude 8, being observable even through small instruments. If it continued with a similar trend, it could become visible to the naked eye in mid-May, before its perihelion, when the comet was to approach within the orbit of Mercury to only 0.25 AU from the Sun. One of the projects in which the TAR (Remote Open Telescope) telescopes are working, located at the Teide Observatory

(IAC), is to monitor the evolution of the morphology of comets. And Comet C / 2019 Y4 (ATLAS) has been one that he has focused his attention on. Taking advantage of the pair of 0.5 m wide-field telescopes, equipped with state-of-the-art Super-CMOS cameras, images were obtained by recording its coma, the atmosphere surrounding the cometary nucleus, which reached a size of about 500,000 km. As well as the detail of its central condensation, from which a narrow ionic tail started. In mid-March, the comet slowed its rapid increase in brightness, something that is usual in this type of very long period comets, reducing its gaseous emission activity on its final approach. Just then, Covid-19 forced the closure of professional facilities
