Estimated ZHRr

The following graph is provided by Mr.Hirofumi SUGIMOTO in Japan.

 

  • 39 observed data.
  • radiant information : Perseids
  • CHR_r means the number of meteors subtracted sporadics from total.
  • ZHR_r = CHR_r * 1/sin(h) (h:radiant elevation),(excluding h < 20deg.)
  • The sporadic meteor is calculated from past data.
