Perseid Meteor Shower 2004
 
August 12, 2004, amateur group of HRC Astronomy dept established a camp beside the K1 observatory because of perseid meteor shower. This observer team was consist of about 20 ones who viewed the sky by their bright ready eyes. They record meteors properties such as color, magnitude and constellation.
The observers arranged in 4 group, and each group observe a quarter of sky.
 
G.1) North
  • Molood Momenbeyk

  • Hajar Vakili

  • Azadeh Fahimgolestane

  • Fahimeh Rahmani

 
G.2) South
  • Nasim Khosravi

  • Mina Soltangheys

 
G.3) East
  • Marzirh Pooramrollahi

  • Zoya Shokoohi

 
G.4) West
  • Zahra Boroojeni

  • Zahra Mohagheghian

  • Sahar Boroojeni

 
After a good observational night, they calculated their results and reported in following text:
 
Observation Place : K1 observatory, Isfahan, Iran
Date of observation: Aug 12, 2004
Time : 20:30 - 00:30 (UT)
Number of meteors in maximum (N) = 115
Population index (R) = 2.6
Limited magnitude (LM) = 5.5
Maximum altitude of Perseus constellation (D) = 40°
Time of maximum : 20:30 - 21:30
 
So according to equation ZHR = N*R(6.5-LM)/Sin(D), this parameter will be calculated.
ZHR = 465
 
Then the meteors properties are arranged in the following tables:
 

Constellation

Number of Meteors
Andromeda 8
Aquarius 7
Aquila 14
Aries 2
Auriga 15
Bootes 2
Camelopardus 8
Capricornus 14
Cassiopeia 16
Cepheus 10
Cetus 11
Corona borealis 8
