How to spot Perseid meteor shower later?


Dear children of God,

Few hours from now we will again observe the peak of Perseid meteor shower. However, most Filipinos won't be able to observe it or will just get frustrated because they won't be able to focus their attention to the spot where the radiant emanates. In most cases, they would dismiss this annual phenomenon as a futile attempt of seeing the event.

So, how will you direct a typical Filipino to spot the Perseid meteor shower?

First, face the northern part of the sky.

Second, ask them if they are familiar of Pleiades star cluster. For sure, they would shy away from you. But ask them if they are familiar of the rosary and most likely they would reply with a big yes. I encircled the Rosary star cluster in the figure above which I print screen from Stellarium application. In astronomy it is Pleiades star cluster but for us this is a mere asterism fondly referred by Filipinos as rosary.

Third, direct your attention just below the asterism and you will find the Perseus constellation. Recall that meteor showers are named after where the radiant emanates. Since it is within the field of Perseus constellation therefore it shall take the genitive form so from Perseus it becomes Perseid.

Fourth, verify if it is indeed Perseus. Check for the "W" or "M" pattern just below in the left side of the star pattern. In the right is an irregular  hexagonal pattern and in the left is a triangle pattern.

Lastly, take note that at 5:34am this upcoming morning you will observe the peak of the meteor shower. It means that in previous days and after the peak you can still observe the meteor shower but it would only provide a sporadic occurrences.

Clear skies,

siraris
