Keywords:Scintillation, Stellar image 9, Star alutitude, Luminosity variability


We investigated the correlation between scintillation intensity, which is the apparent luminosity change of celestial objects and a major barrier to astronomical observations, and humidity, temperature, wind direction, and altitude.
Details of the experiment are as follows.
On March 30, 31, and April 3, 2023,astronomical observations were made on the school's rooftop; a total of 50 astrophotographs were taken over a 5-second period, and the luminosity counts for each photograph were measured with the luminosity measurement tool Stellar Image 9 to calculate the coefficient of variation to determine the rate of stellar luminosity variability.
The results show that there is a clear correlation between the altitude of the star and the luminosity variability.
The relationship with other conditions is currently being analyzed.
