2020-06-12: Slow-Moving CME

Very slow-moving CME (~40 k/s) with cavity and structured prominence in southwest. Event is in progress when observations begin at 17:06:08 UT on June 12. Still in field-of-view when observations end on June 13 at 02:21:05 UT. Likely related to slow streamer blowout seen in LASCO C2 on June 13-14. Some prominence material falls sunward as structure moves outward. Remaining prominence material swirls within cavity and fades, possibly due to heating and/or more material falling sunward. CME becomes asymmetric and moves non-radially (equatorward) likely due to pressure from adjacent polar coronal hole.
