| Term: | Hyder flare |
| Definition: |
A filament-associated two-ribbon flare, often occurring in spotless regions. The flare is generally slow (30-60 minutes rise time in Ha and x-ray) and follows the disappearance of a previously quiescent filament. The Hyder flare is named for Dr. C. Hyder, who published studies of such flares in 1967. |
