Nov. 1, 2019:\u00a0<\/strong>Breaking a string of 28 spotless days, a new sunspot (AR2750) is emerging in the sun\u2019s southern hemisphere\u2013and it\u2019s a member of the next solar cycle. A picture of the sunspot is inset in this magnetic map of the sun\u2019s surface from NASA\u2019s Solar Dynamics Observatory:<\/p>\n

How do we know AR2750 belongs to the next solar cycle? Its magnetic polarity tells us so. Southern sunspots from old Solar Cycle 24 have a -\/+ polarity. This sunspot is the opposite: +\/-. According to\u00a0Hale\u2019s Law<\/a>, sunspots switch polarities from one solar cycle to the next. AR2750 is therefore a member of Solar Cycle 25.[…]<\/p><\/blockquote>\n
