Result of ηAquarids(2010)

The actvity level in 2010 was same as annual yaer. Observed peak was about 2.0, and estimated activity level was 1.5. The peak time which came around λo46°.2 was later than annual year. On the other hand, observed data had large errors.
2010 ηAquarids had two estimated compornents.
