Sure, pilgrims should not go to pilgrim mass at the Cathedral of Santiago just to watch the
botafumeiro swing. But the advice to just let themselves by surprised (or not) is easier given by those who have seen it in action not only once but several times already.
It has already been mentioned that there are four
misa del peregrino every day: at 7:30, 9:30, 12:00 and 19:30. Having watched a few times in recent days in live streaming, I can say that it can swing at any time, even at 9:30. Mass at 12:00 and 19:30 is more likely an occasion for observing it but it is no guarantee, not even in this Holy Year where presumably more parochial groups travel to Santiago than in normal years as well as individuals who are also willing to donate a considerable sum to set this big censer in action.
Some of the feast days are coming up when the botafumeiro will swing as part of a Solemn Mass. From the Cathedral's website:
- Lunes 23 de mayo – Fiesta de Clavijo. A las 19:30 h. Misa capitular. Funcionamiento del Botafumeiro.
- Domingo 29 de mayo- Ascensión del Señor. A las 11:40 h. Procesión del Cabildo y Misa solemne presidida por el Arzobispo. Funcionamiento del Botafumeiro.
- Domingo 5 de junio – Pentecostés. A las 11:40 h. Procesión del cabildo y Misa solemne, presidida por el Arzobispo. Funcionamiento del Botafumeiro.
BTW, taking photos and videos of the swinging botafumeiro are apparent tolerated. However, at the beginning of EVERY pilgrim mass, an announcement is made that says:
The use of cameras and mobile phones is forbidden. It is Mass, after all, from beginning to end.
