| datatype: | char | ucd: | pos.bodyrc;pos.heliographic |
| xtype: | utype: | helio | |
| description: | Solar source location (Loc) of the associated eruption in heliographic coordinates. S25E16 means the latitude is 25 deg south and 16 deg east (source located in the southeast quadrant of the Sun. N denotes northern latitudes and W denotes western longitudes. Entries like SW90 indicate that the source information is not complete, but we can say that the eruption occurs on the west limb but at southern latitudes; if such entries have a subscript b (e.g., NE90b) it means that the source is behind the particular limb. This information is usually gathered from SOHO/EIT difference images, which show dimming above the limb in question. Completely backside events with no information on the source location are marked as BACK. | ||
