Capricornids/Sagittariids
Very weak and wide activities were sometimes observed. But this activity is not clear. It has a possibility to see small activity after calculate many worldwide radio data. Although some papers in ’70 were published, this meteor shower is not clear after that.

ο-Cetids shows a activity from the middle of May to June. Although Meteor Data Center published by International Astronomical Union (IAU) also records “ο-Cetids Complex", there is not enough record and information. Although the activity level was recorded as “Medium", recent reseults were recorded as “Low". Radio Meteor Observation in the world does not catch a clear activity since 2006.

Arietids
Arietids is the most famous and biggest meteor showers in daytime meteor showers. There are a lot of observed records and data. In addition, it is possible to catch video or visual meteor observation before sun-rise. Although the max date is λ⊙=76°.7(Jun.7) by International Meteor Organization, some peak dates are publishd by some papers. The number of meteor echoes increase from 1st June, the maximum comes around 8th-10th June.

This project caught clear activity profiles during the period 2006-2019. The number of meteor echoes increases from λ⊙=72°. During the maximum period, ζ-Perseids comes same time. This project, therefore, separates observed activity profile to two comporntents. You can see more detail results as following “More Information" URL.

ζ-Perseids
ζ-Perseids comes at same period of Daytime Arietids. Since Radio Meteor Observation (forward scattering) is impossble to separate meteor showers, this project adopts the separation with two compornents. Although International Meteor Organization (IMO) publishes follwoing information, other papers say different activity profiles. For example, IMO is λ⊙=78°.6, one paper says λ⊙=83°.5(Jun.14). This project is also later peak time than IMO.
