The CTA LST telescope is back in operation. After a few weeks dedicated to cleaning the site and checking the telescope subsystems, the first sky data were taken in early February.

Observations of the standard candle of gamma-ray astronomy, the Crab Nebula, on the nights of February 4 and 5 confirm that the telescope performance has not suffered any significant degradation. The data analysis has been led by IFAE, with the participation of Chaitanya Priyadarshi and Abelardo Moralejo.

IFAE members Manel Martínez, Rafa García and Pau Llanes took part in the on-site preparations for the restart of operations. Oscar Blanch and Daniel Kerszberg contributed to the recommissioning of the telescope camera, and the data analysis was led by IFAE, with the participation of Chaitanya Priyadarshi and Abelardo Moralejo.
