المملكة: Jeddah Astronomy: Two sunspots return to the surface within 48 hours
Field of view during the next 48 hours, coinciding with the sun’s continued rotation around its axis.
Abu Zahira stated that these two regions were last seen on December 12, when they were in direct confrontation with the Earth, during which they recorded a number of moderate and low-intensity solar flares, without any severe solar events of the higher categories being recorded.
Weak possibility of impact on space weather
He pointed out that Recent monitoring data did not show any Large coronal mass emission behind the southeastern edge of the sun during the past days, which reduces the possibility of direct impacts on space weather near Earth when these areas reappear.
The President of the Astronomical Society in Jeddah stressed that monitoring these areas is of special scientific importance, pointing out that sunspots do not necessarily lose their activity after their temporary disappearance behind the sun’s disk, as they may resume producing flares and solar emissions when they return to the fore, depending on the degree of complexity. Its magnetic structure.
He explained that the current solar scene is based on an image taken by the Solar Dynamics Observatory in the 171 Angstrom range, which is a wavelength that highlights the hot plasma in the solar corona, and helps scientists track the development of active regions and the magnetic structures associated with them with high precision.
Abu Zahra concluded his speech by stressing that solar physicists will continue to closely monitor regions 4294 and 4296 as their return approaches. To the field of direct monitoring, in order to evaluate any possible renewal of solar activity, and monitor its possible repercussions on the space environment surrounding the Earth.
