Daytime Arietids/ζ-Perseids

To Daytime Meteor Showers Results

Since Daytime Arietids and ζ-Perseids show ctivities in the same period, it is difficult to separate them. In this research, therefore, try to estimate two compornents. Their activities show the strongest activity level in all daytime meteor showers.

Results of Daytime Arietids/ζ-Perseids every year

Daytime Arietids/ζ-Perseids Components

The following graph shows the separation of Long term activity profile(2006-2019). One is Comp-A(Orange-line). Another is Comp-B(Blue-line). Comp-A is estimated as Daytime Arietids (171 ARI). Comp-B shows an estimated Daytime ζ-Perseids (172 ZPE). Lotentz(red-line) is total activity profile (Comp-A + Comp-B).
