Discovering Asteroids

We have recently participated in the Project "INTERNATIONAL ASTRONOMICAL SEARCH COLABORATION-IASC" [1] in the group "ALL COLOMBIA ASTEROID SEARCH CAMPAIGN" from April 8th to May 6th 2018. We analyzed the photographies provided by IASC through Astrometrica software [2]. The images were captured by the observers N. Primak, A. Schultz, S. Watters, J. Thiel, T. Goggia, employing the 1.8-m f/4.4 Ritchey-Chretien telescope at Pan-STARRS 1-Haleakala-Hawaii (Observatory code F51) [3]. We have obtained the finding of twelve asteroids which, for the time being, have the status of PRELIMINARY in the IASC. We have calculated the orbital parameters for 7 asteroids and we've found of great interest the asteroids OUN0016 and OUN0025. On April 8/2018 the asteroid OUN0016 was closer from the Earth's orbit and we estimate it will remain so until roughly July 25/2018; then it will begin to move away. It won't intercept at any point the Earth orbit; it has the lowest period which is very similar to the Earth's, also it has the smallest diameter
