星空有约|太阳脸上长了雀斑：个头不小、数量可观

Core Viewpoint - The recent appearance of sunspots on the sun's surface indicates a peak in solar activity, which is part of the 25th solar cycle, and presents an opportunity for public observation [1][5]. Group 1: Sunspots Overview - Sunspots are dark spots on the sun's photosphere that vary in size, number, position, and shape daily [1]. - They typically appear in groups or clusters, with each active region containing multiple sunspots that form a complex magnetic field system [3]. - The current sunspot group was first observed on November 30 and is expected to be visible for several days due to the sun's rotation [3][5]. Group 2: Solar Activity and Implications - The current period marks the peak of the 25th solar activity cycle, characterized by a significant increase in the number and intensity of sunspots [5]. - The presence of sunspots indicates abnormal solar magnetic activity, which may lead to phenomena such as auroras [5]. - Despite the increased solar activity, the impact on human life and production is minimal, and there is no need for public concern [5]. Group 3: Observation Guidelines - The sunspot group provides a unique opportunity for the public to observe sunspots, particularly during mornings and evenings when atmospheric conditions are favorable [7]. - For safe observation, it is recommended to use telescopes equipped with solar filters, as direct viewing can cause serious eye damage [7].
