(continued from part 1)

There are "white light" faculae on the north east limb, and it looks like a pore or spotlet is associated with this activity:

0915 UT. WO FLT 110, Lunt solar wedge, 2.5x Powermate, DMK21

The tall prominence on the north east limb, clearly visible in the CaK overview, had almost but not quite disappeared by mid morning:

0958 UT. Solarscope 60, 2.5x Powermate, DMK21 - special processing to show faint prominence more clearly

There is significant prominence activity on the south east limb:

0956 UT. Solarscope 60, 2.5x Powermate, DMK21

1400 UT. Solarscope 60, 2.5x Powermate, DMK21

Meanwhile the large "suspended" prominence on the NW limb appears to be collapsing and fading:

0954 UT. Solarscope 60, 2.5x Powermate, DMK21

1358 UT. Solarscope 60, 2.5x Powermate, DMK21
