Quadrantids Results(2007)

In 2007, the activty level as same level was kept around peak time. The clear peak, therefore, was not caught around peak time.
Quadrantid estimating profile was two compornent. One is background activity, the other is main peak. Using this results, the activity level was similar as annual year.

Activity Level (using worldwide data)

Observed Peaks

Time(UT) Solar Long. Activity Level
Jan. 3 21h 283°.025 4.52 ± 0.36
Jan. 4 03h 283°.280 4.64 ± 0.57

Estimated Compornents of Quadrantid activity

Comp.No. Peak Time(UT) Solar Long. A(max) FWHM(hr)
QUA07C01 Jan. 4 00h00m 283°.14 1.5 -12.0/+12.0
QUA07C02 Jan. 4 00h30m 283°.158 4.5 -5.0/+4.0

Parameter

  • Radiant : α = 230°.1, δ = +48°.5
  • Radian Elevation : 15° < h < 80°
  • Using data within ± 0.75 σ in all observed data.

Reference

  • Structure of meteor activity is estimated by "Lorentz profile".
  • Observed data provided by RMOJ and RMOB
