CME Note: [IN REVIEW] Halo CME visible in SOHO LASCO C2 and C3 imagery. STEREO A COR2 is in a data gap during this event. The source of this CME appears to be an M1.0 flare from AR13757 (N15E20) peaking at 2024-07-21T16:31Z. Filament ejecta is visible in SDO/AIA 304 and GOES SUVI 304 with significant northward deflection. The bulk of the CME is likely the brighter portion visible in SOHO LASCO C2/C3 difference imagery to the NE. The fainter halo portion is possibly associated with this event, though there is some uncertainty due to a lack of visible dimming to the south of the source location.

Solar Active Regions and flaring: The solar flaring activity was at high level during the last 24 hours, with several C-class flares and six M-class flares. The strongest flare was GOES M3.9 flare from NOAA active region
(AR) 3762 which peaked at 04:04 UTC on Jul 22. During the flare, the source region (AR 3762) of the flare had beta configuration of its photospheric magnetic field. Apart from NOAA AR 3762, NOAA AR 3757 (beta configuration) and NOAA AR 3744(beta configuration) also produced M-class flares. The NOAA AR 3751 has the most complex magnetic configuration (beta-gamma-delta), but it has only produced few C-class flares. The solar flaring activity is expected to be at moderate to high levels over the next 24 hours possibly with few M-class flares and a low chance for isolated X-class flares.

Coronal mass ejections: A halo coronal mass ejection (CME) was first observed in the SOHO/LASCO C2 field of view around 16:28 UTC on Jul 21. CME was associated with a M1.0 flare from NOAA AR 3757 (N15 E20) and an eruption of a very twisted filament with the main propagation direction towards North. The first estimation shows projected speed of the CME to be about 730 km/s which brings expected arrival time at Earth to be around
05:00 UTC on Jul 24. A M1.4 flare occurred with a peak time 09:35 UTC on Jul 22, produced by NOAA AR 3744. Associated Type II radio emissions were detected at 09:26 UTC on Jul 22, during the flaring activity. The associated CME will possibly have Earth directed components. Further analysis will be carried out once the corresponding LASCO coronagraph images are availble. No other Earth-directed CMEs were detected in the available coronagraph observations during the last 24 hour.

Lead Time: 4.18 hour(s)

CCMC Rules of the Road: CCMC requests that users notify the CCMC, CME model/technique developers and submitting forecasters/researchers before performing event and validation studies with data from the CME Arrival Time Scoreboard. It is recommended that such studies be performed with the knowledge and collaboration of developers and submitting forecasters/researchers.
