What I tell you three times is true! Here it is of course magnetic reconnection, possibly explaining an unusual confined flare (SOL2011-11-03). It is happening at the HFT (hyperbolic flux tube], at the BPSS (bald patch separatrix surface, and at the unlabeled spine-fan configuration at the right ot the cartoon. This complexity, it is argued, explains the discrepancies noted with respect to CSHKP, which of course would not readily explain a confined flare in any case.
