Clint Jean Louis and Araceli Sergio launched the chupinazo rocket today at noon to officially begin the San Fermín festivities in Pamplona [1, 2].

The event marks the start of one of Spain's most iconic cultural celebrations, drawing global attention to the region of Navarra for nine days of traditional events [2, 4].

Standing on the main balcony of the City Hall overlooking the Plaza Consistorial, the two officials triggered the rocket that signals the festival's commencement [2, 3]. Jean Louis serves as the deputy director of emergencies for Navarra, while Sergio is a nurse with the Tafalla mobile intensive care unit [1, 2].

The crowd in the plaza was dense as residents and tourists gathered to witness the opening moment. More than 12,500 people were congregated in the Plaza Consistorial for the event [5].

The chupinazo is the essential precursor to the festival's diverse program, which includes the famous running of the bulls, concerts, and bullfights [4]. This tradition transforms the city into a hub of activity, blending religious observance with public celebration, a cycle that repeats annually every July.

Local authorities coordinated the event to ensure the safety of the thousands of attendees gathered in the city center [2, 3]. The transition from the rocket fire to the general celebration typically involves a surge of energy throughout the streets of Pamplona, as the city enters a period of intense tourism and cultural display.

The chupinazo is the essential precursor to the festival's diverse program.

The selection of emergency medical personnel to launch the chupinazo reflects a recurring trend of honoring public health and safety workers during the festival's opening. By centering the start of the event on the deputy director of emergencies and a mobile ICU nurse, the city acknowledges the critical infrastructure required to manage the massive crowds and inherent risks associated with the San Fermín celebrations.
