    We saw a sunspot on February 11-13, then it was gone. Typical of sunspots recently, it was only seen briefly; this one was a relic of Solar Cycle 23, according to its magnetic signature. For at least a couple of years now, we've been expecting Solar Cycle

    Sunspots returned this week, or rather, one did, but it is an old Solar Cycle 23 spot. Sunspot 1012 has been visible the last couple of days, February 11-12. It is down near the Sun's equator, typical for spots from a previous cycle. It's nice to have a s
