... Arietids and ζ-Perseids

Northern ω-Cetids

icon Result
Northern ω-Cetids peak is around solar longitude λ=47°.5. This peak time is lacated in decrease process of η-Aquariids. It is therefore difficult to see a clear activity. Although the activity level in 2014 increased around λ=47°.6 - 48°.0, it was uncertain.

Southern ω-Cetids

2019 Southern ω-Cetids activity increased around λ=49°.2`50°.0 (estimated peak time was around λ=49°.6). The activity in 2012 inreased too.
If long time activity profile separates two compornents, one compornent (Comp-A) is esteimated that peak time was around λ=45°. Another (Comp-B) has a possibility of this meteor shower. Comp-B has a peak time around λ=49°.5.

ε-Arietids

icon Result
Although some weak activities were observed in 2008, 2011, 2014 and 2017, they are too weak activity to say clear activities. If long time activity profile separates two compornents, one compornent (Comp-A) is esteimated that peak time was around λ=45°.5. Another (Comp-B) has a possibility of this meteor shower. Comp-B has a peak time around λ=48°.5. Since the estimated peak activity level was 0.1, however, it is difficult to separate ε-Arietids and usual activity.

ο-Cetids

There was no clear activiy since 2006. Although the activity level in 2018 increased around λ=59°.6, it was too short peak period to say that it was caused by this meteor shower.
