I managed to capture today’s sun activity, taken in Hydrogen-Alpha (Hα) wavelength, highlights the active sunspot regions present on the solar disk at the time of observation.
Sunspot Activity in the Image:
This solar image clearly shows multiple active sunspot regions labeled according to their NOAA designations:
• 4018, 4019, 4020, 4021, 4022, 4023, 4025, 4028, 4029, 4030, 4031, 4033, 4034, 4035
These sunspots are areas of intense magnetic activity where the Sun’s magnetic field is highly concentrated, leading to cooler and darker regions on the solar surface.
This image provides a detailed view of the Sun’s chromosphere, allowing us to observe the intricate structures of sunspots and their surrounding active regions in Hα light, which reveals dynamic solar features such as filaments and prominences.
