Issued on 2023 Sep 12 0759 UTC
South-East partial halo Coronal Mass Ejections (CME) was detected in the SOHO/LASCO coronograph images on September 11 at 10:15 UTC with an angular width of about 210 degrees and a projected speed of 300-325 km/s as estimated by the CATus tool. No associated signature on the visible solar disc seen from Earth was identified; therefore we believe that the source region of this CME is far side.
Another full halo CME was detected on September 11 at 23:15 UTC in the SOHO/LASCO coronograph images with a South-East main component and with a projected speed of 512 km/s as estimated by the CATus tool . No clear associated signature on the visible solar disc seen from Earth was identified, further investigation and analysis of this event are ongoing.
