[O08-P09] Observation of solar radio waves and their relationship to sunspots
Keywords:solar radio wave, sun spot
Motive Purpose Correlation with solar radio waves will be investigated using data from sunspot observations that have been conducted for many years.
method Observe solar radio signals using BS antennas, boosters, detectors, and PASCO, and correlate them with the number of sunspots at the National Astronomical Observatory of Japan.
hypothesis Experiment 1 By pointing it in the direction of the sun, the value increases and solar radio waves can be observed.
Experiment 2 Since the sunspot number and the solar radio wave at a wavelength of 10.7 cm show similar changes, the same changes are observed in the solar radio wave at a wavelength of 2.5 cm.It also shows a positive correlation.
result Experiment 1 When pointed at the sun, it was 1.81V, and when pointed at true north, it was 0.34V.
Experiment 2 For solar radio waves, the values decreased immediately after the start of the measurement.The correlation was -0.55033, which is negative. This is contrary to our hypothesis.
consideration Experiment 1 The difference in values was sufficiently large to suggest that solar radio waves were being observed.
Experiment 2 Regarding the results being contrary to the hypothesis, this may be due to the insufficient number of data and the failure to account for changes in solar radio values during the day.
