The Solar System research group at the Instituto de Astrofísica de Canarias (IAC) is participating in the international programme to keep a closet track of asteroid 2024 YR4. The aim is to determine its orbit with the highest possible precision before it stops being observable by ground based and satellite telescopes in April, and so improving our value of the probability that it will impact the Earth in 2032. In this context several telescopes of the Canary Observatories of the IAC are playing an outstanding role in this observing campaign: The Gran Telescopio Canarias (GTC) at the Roque de

The team led by Claudia Gutiérrez from the ICE-CSIC and IEEC has used the Gran Telescopio Canarias (GTC) and the Nordic Optical Telescope (NOT), at the Roque de Los Muchachos Observatory, of the Instituto de Astrofísica de Canarias (IAC), in La Palma. The CSS161010 burst reached its maximum brightness in just 4 days in a small galaxy 500 million light-years away from us. An international scientific team, led by the Institute of Space Studies of Catalonia (IEEC) and the Institute of Space Sciences (ICE-CSIC), has managed to detect an exceptionally fast and bright cosmic burst in a small
