L: Loop
LS: Loop and Shock Candidate
Note: Second of two CMEs seen to the north and west in SOHO/STEREO A imagery starting around 2023-08-04T04:17Z which is inferred to be in association with a long duration M1.9-class solar flare near the vicinity of Active Region 3386 (N12W46) due to the complex, sympathetic eruptive signature containing multiple areas of dimming. The CME front seen first near 2023-08-04T04:49Z appears to be embedded within the first, and is directed more westerly. The overall eruptive signature is characterized by an erupting/disappearing loop starting around 04:04Z near the vicinity of Active Region 3386 seen best in SDO 171 occurring before the M1.9-class flare as well as opening magnetic field lines off the western limb seen in this wavelength. SDO 304 shows a near-simultaneous filamentary surge north of the flaring Active Region 3386 and south and east, towards the direction of the observing spacecraft, starting around 03:55Z, followed by a minor sympathetic filament liftoff closer to 05:30Z. SDO 193 shows three distinct areas of dimming: northwest and southeast of the Active Region during and occurring with the flare, then sympathetic dimming north and east of the Active Region in association with the northern filament surge.
