BTW, I should add that this meteor shower typically produces about 100 meteors per hour:
In[5]:= Entity["MeteorShower", "Perseids"]["PeakZHR"]
Out[5]= Quantity[1.0*10^2, 1/("Hours")]
Although some predictions are claiming that this years shower could be double that. Predicting meteor shower performance is more art than science and can vary from one location to the next given that there can be narrow bursts that favor one location and not another.
