The perseidas, popularly known as the tears of San Lorenzo, are a meteor shower of high activity. But don't worry, this does not mean that the Armageddon as Michael Bay painted it for us, but it is one of the most important astrological events of the year that has thousands of followers.
Vision hindered by the Moon
Known in the countries of Catholic tradition with the name of tears of San Lorenzo for being on August 10 the day of this saint, in the Middle Ages and the Renaissance the Perseids took place the night he was remembered, in such a way that they were associated with the tears that San Lorenzo shed when he was burned at the stake . This phenomenon has its origin in comet 109P / Swift-Tuttle, and in itself they are high-speed meteors that go to 59 km / s and radiate from the constellation Perseus. In themselves they are visible in many places, especially outside urban centers where light pollution is scarce.
The Perseids usually have their peak on today's date precisely on August 10, but this year experts have announced that the we will see better between days 12 and 13In fact, this morning they will reach their peak of visibility. According to the National Geographic Institutel, "maximum rainfall activity is expected to take place between 4 a.m. and 5 p.m. on day 13 (official hours on the peninsula). So the best night for observation should be August 12-13; unfortunately the almost coincidence of the maximum with the full moon –full moon for this August 15– complicates the observation. If we have patience we can wait for the Moon to hide (about 5 hours of official peninsular time) and take advantage of the short period of time until the beginning of dawn.

The place of observation can be any as long as it provides a dark sky. It is preferable to observe from a place that has few obstacles to sight (such as buildings, trees or mountains), and not use optical instruments that limit the field of vision. Although the persecutions seem to come from the constellation of Perseus (hence its name), they can be seen anywhere in the sky. It is advisable to look towards the darkest areas, in the opposite direction to the position of the Moon if the observation is made before sunset. The most comfortable is to lie down and wait for the view to get used to the darkness.
The number of observable meteors per hour is very variable. In a very dark place and with the radiant high above the horizon can exceed one hundred. However, the number of meteors observed per hour can vary very rapidly depending on the density of fragments in the comet's wake, so "specific predictions about specific number of meteors depending on the day and time are difficult to make and are usually affected by high uncertainty.

Those who have a telescope and the option of being in a good place with appropriate conditions can see them without problems, but if we want to see them equally well although we have no means, then our mobile becomes the best possible option for it.
