St Raphael Church in Morningside will be celebrating the feast of St Rocco.  At 4 pm there will be a mass, and immediately afterwards there will be fireworks as they leave the church.
You should hear the fireworks around 5 pm, although it will be too light out to see them.  Then after it gets dark, there will be more fireworks.  So be prepared to hear both sets of these today, since the church is right next to Heth's field at Hampton and Chislett.
