Two flares occured successively in distant active regions.

Correlation plots at 17/34 GHz. The first peak at 5:24UT is from the eastern AR #8421 in the box (see below), while the second peak at 5:47UT is from the western AR #8419. It seems that these two ARs are connected by (a) huge faint loop(s).

Full disk image at 17GHz (01:31:22UT).
