while EIT ran a high-cadence multi wavelength program
Mercury is now present in C2 images, moving L-R
away from the Sun

04:25 UT Last C2 image prior to Mercury transit
04:31 UT Last C3 image prior to Mercury transit
16:06 UT First C2 image following Mercury transit
16:18 UT First C3 image following Mercury transit
<16:06 UT S East Fairly wide ragged front already clear of
C2 field of view, leading edge at ~15 Rs.
Slight cavity, some gusty outflow
16:06 UT N West Very faint front
