The persecuted are also known in Catholic countries with the name of tears of San Lorenzo, because August 10 is celebrated his saints. In the Middle Ages and the Renaissance the persecutions took the night when it was remembered, in such a way that they were associated with the tears that San Lorenzo poured when being burned on a grill. The oldest record that has the activity of the persecutions in the year 36 d. C., of the Chinese historical annals where a peak of meteors in those dates is mentioned. But it was not until 1835 when the Belgian astronomer Adolphe Quetelet shows that a meteor shower occurs, cyclically in August, with its radiant in Perseus. Each year at the beginning of August our planet crosses the orbit of Comet 109P / Swift-Tuttle, which passed close to the Sun for the last time in 1992, the National Geographical Institute explains on its website, which indicates that its orbit is full of small particles. Most are as small as a grain of sand and when they cross our planet they hit the atmosphere at a speed of more than 210,000 kilometers per hour.
The night that joins the 12th with the 13th of August will reach its maximum expression approaching, from 22:00 on August 12 (Peninsular time) until 10:00 of the 13th, reaching up to 200 visible meteors per hour.
According to Miquel Serra-Ricart, an astronomer at the IAC, this year there will finally be a very dark night due to the absence of Luna and explains that "if we place ourselves in a place without light pollution and without clouds, the show is assured". Antiquus can not help being that night watching such a wonder ... we hope you can enjoy it too. Sources: 20 minutes National Geographic Institute Wikipedia
