An approximate 10-degree filament eruption, centered near S36E33, was observed in GONG H-alpha imagery beginning at 09:58 UTC on November 24, 2021. 

An associated coronal mass ejection (CME) was observed in SOHO/LASCO C2 imagery beginning at 14:12 UTC on November 24 and WSA/ENLIL modeling shows an arrival time late on November 27.1

Mostly quiet geomagnetic field conditions are expected on November 25 and 26, followed by quiet to unsettled levels early on November 27 with the arrival of a negative polarity CH HSS.

By late November 27, the CME is expected to enhance activity to unsettled to active levels with a chance for G1 – Minor geomagnetic storming.
