"We saw a string of zero-sunspot days over the past couple of weeks, but this week saw a brief but significant sunspot that lasted only a couple of days. Sunspot 990 emerged as a tiny speck over April 14-15, but it was definitely a Solar Cycle 24 spot. Not only was the polarity of this region correct for the new Cycle, but it was far north above the Sun's equator, which is what we expect for a sunspot from an emerging solar cycle. The only previous Cycle 24 activity was close to the solar equator."
