ESPRESSO Science Verification took place at the end of August and the beginning of September 2019. It was spread over two visitor-mode nights, requiring seven hours of observations taken in service mode. The weather conditions (strong winds and poor seeing conditions) and some telescope problems (failure of guide cameras) hampered the first two nights and additional time was granted to finish the top-ranked programmes. In response to the call for ESPRESSO science verification, 16 proposals were submitted, 10 of which were scheduled for a total of 25 hours of observations. A slight oversubscription of the available time was planned to allow for the prevailing atmospheric conditions. The seven top-ranked programmes were fully completed.
