2016-05-17T17:06:22 --> 2016-05-17T23:48:54
Transition region loops (SJI 1330 and 1400) that are seemingly pinched at the sites of converging photospheric flows (as seen in SJI 2832 sequences) suggest resistive flux emergence is taking place. The magnetic reconnection / cancellation taking place at and above the convergence sites create longer loops that straddle multiple flow cells. The convergence sites are also locations of enhanced emission in the SJI 1330, 1400 and 2796 channels (i.e. UV burst or bombs).

On 18 May 2016, the GOES X-ray (1-8 A) background decreased from the B3 to B2 level. This may have been caused by AR 12542 and 12545 rotating deeper behind the west limb. There is little indication that any of the disk regions decayed. This can be confirmed by making light curves of the individual regions.
