Active region has produced a flare that is
large (typically GOES high-M or X-class) and is associated with Fermi
LAT nuclear-line or
high-energy gamma-ray emission, typically with a fast and broad CME (if
produced one such flare, it will probably produce at least one more).
To determine whether a large flare is associated with Fermi LAT
high-energy gamma-ray emission contact Gerry Share, who will consult with the Fermi LAT team.
Active region has an area >~1000 micro-hemispheres and is classified "beta-gamma-delta", and in addition has an "Island Delta" sunspot configuration with the following properties, of which the first three are most important:
