KOMPAS.com – Perseus meteor shower is an annual celestial phenomenon that always occurs between July and August.
In fact, this phenomenon has been going on since July 17 yesterday. However, the peak of the new Perseid meteor shower will occur on August 12, 2019.
Amateur amateur Marufin Sudibo said the meteor shower will end on August 24, 2019.

According to the site Southern skyPerseus meteor shower is one of the most popular meteor shower among observers, especially those in the north.
Because the Perseid meteor shower always gives a show of incredible meteor showers, with about 100 meteors passing through the sky every hour.
"Perseid's meteor shower is really quite heavy. It can produce a maximum of 100 meteors per hour at its peak," Marufin said Kompas.com, Saturday (October 8, 2019).
Marufin explained, the persistent meteor shower is a periodic celestial phenomenon.
That is, the Perseid meteor showers happen every year with a relatively similar schedule of occurrence from year to year, ie. between July 17 and August 24, and the peak on August 12.
Marufin said the meteors from the Perseid meteor shower seemed to come from the constellation Perseus in the northern sky.
"Therefore, this meteor shower is easier to bear than the northern hemisphere. The southern hemisphere, which can see it, is limited to 30 LS in width. It cannot go further south," he explained.
The origin of the Perseid meteor shower
The Perseus meteor shower comes from the remains of the Swift-Tuttle comet's tail comet, which passed through Earth and was observed by astronomers Lewis Swift and Horace Tuttle from America in 1862.
This comet was again observed in 1992 and has a period of 130 years. He will return to Earth in 2126.
As it passes, the comet's tail in the form of rocks experiences ground gravity and enters the earth's atmosphere and burns there.
The dust entering the upper atmosphere will form an overheated plasma along its trajectory and will move at a speed of 60 km / sec.
This is the trajectory of light that passes by observers from Earth as Perseid's meteor shower.
Privileges of Perseid Rainfall
Marufin said the Perseid meteor shower has many differences with other meteor showers.
Starting from the maximum number of meteors (ZEN / ZHR), which is rated as high up to 100 meteors per hour when the sky is in perfect condition.
"Then the source of the Perseid meteor shower is also different from the other meteor rains. All periodic meteor showers are comet crumbs, but only the Perseids have a strong meteor shower, while the parent comet has a rather long period," Marufin explained.
"Another difference is that Perseids has the potential to produce bright or meteors fireball in the peak of meteor shower, "he added.
Can this year's Perseid meteor shower be seen from Indonesia?
Marufin said the actual meteor shower could be seen from Indonesia.
"It's just not perfect in the sky because (at the peak of the Perseid meteor) there is a moon that is only three days away from full moon," Marufin said.
Since the peak of the Perseid meteor is H-3 before the full moon, the night sky will be too bright and the sky phenomena like meteor showers will be hard to see.

In theory, the Perseus constellation was published in the eastern sky at 00.00 WIB. From there, meteor showers can be seen.
"But since there is a moon that is still very bright and sets at just 2.00 West Indonesian time, in practice this meteor shower can only be used from 2.00 West Indonesian time until dawn," Marufin concluded.
