Information (as following list)
| Year | source | Comments (Time:UT) |
|---|---|---|
| 2020 | WorldWide | The peak time was later than annual year. A sub peak was observed. |
| 2019 | WorldWide | Activity Level was weak. Two small sub-peaks were osberved. |
| 2018 | WorldWide | Sub peak(λ⊙=139°.7) was observed before the main peak. |
| 2017 | WorldWide | There was no unusual activity level. The estimated A(max) was 1.5. |
| 2016 | WorldWide | The predicted peak and annual peak was observed.(high activities) |
| 2015 | WorldWide | A(max) was over 3.0. This high activity added to annual activity. |
| 2014 | WorldWide | The peak was λ⊙=140°.0. The activity level was higher ? |
| 2013 | WorldWide | All activity profiles were same as annual year. |
| 2012 | WorldWide | Activity profile was same as annual year. The peak time was earlier. |
| 2011 | WorldWide | The peak time was around λ⊙=139°.95 with estimated ZHR 96. |
| 2010 | WorldWide | Both activity level and peak time were as annual year. |
| 2009 | WorldWide | Double peak(λ⊙=139°.9 and 140°.1) was observed. |
| 2008 | WorldWide | Double peak(λ⊙=139°.6 and 140°.6) was observed. λ⊙=140.0 was unclear. |
| 2007 | WorldWide | The peak around λo140°.2 was observed. A(max) was small. |
| 2006 | WorldWide | The peak was λo140°.05 with A(max)=1.5 |
| 2005 | WorldWide | Double peak(λ⊙=139°.38 and 140°.2) was observed. λ⊙=140.0 was smaller. |
| 2004 | WorldWide | Annual peak λ⊙=140° and the predected peak by Lyytinen were observed. |
| 2003 | WorldWide | The peak was λ⊙=139°.8. λ⊙=140°.5 was sub-peak(?). |
| 2002 | WorldWide | The peak was λ⊙=139°.8. λ⊙=140°.8 was sub-peak(?). |
| 2001 | WorldWide | It was not enough to analyze the profile of Perseid activity. |
| 2000 | Misato Obs. | The peak was observed around 19h 12th with HR85 and many long echoes. |
| 1999 | Chigusa HS | This was provided by Listening-method. (*This is my first observation!!) |
