The cartoon

A severely utilitarian cartoon, in grim black and white, specifically describing the flare SOL2000-03-01, a C-class flare well observed in hard X-rays and microwaves. Though drawn for this specific event, it nicely illustrates the connectivity of the field and its current sheet, as envisioned in the well-beloved CSHKP. Here "light bridge" refers in the usual sense to the sunspot structure. This excellent paper, among the first to make use of "frequency-agile" microwave imaging spectroscopy, also invokes the thick-target that forms the other pillar (with CSHKP) still common two decades later.
