This is a sublist of large events on the front side of the sun, ie. that fall at least partially within E90-W90 longitude. This list covers January 1993 through June 1994. This list includes all obvious arcades, but also other large scale events that may be only loosely classifiable as arcades. [48 Events] The line items are: ET, event type, a brief discription; HC, coronal hole relationship, "NPCH" being north polar coronal hole, "ex" being a low latitude extension; OE, being other events, either solar or interplanetary. ***January 12, 1993. 00:00UT - 00:00UT.
