Introduction

The Nuggets have been watching the current solar cycle as it begins (see Nuggets [A], [B], [C], [D], [E]); the amazing thing about these Nuggets is that they began in December 2008, when we already were baffled by the lengthy [sunspot] minimum period. It has taken almost two years now for us to reach a level of activity where we might have a major flare, as described below, but not yet.

It has been amazingly slow to set in, but we are beginning to get scientific results on flares from the new cycle. We discuss one of them in this Nugget, and another in the next Nugget.

The Spots Return!
