Solar alert

Issued on 2023 Apr 04 1158 UTC

The partial halo CME was observed in the morning of April 03, first time seen in the SOHO/LASCO C2 field of view at 07:36 UT. The CME’s velocity was about 300 km/s (as reported by CACTUS software), and its angular width was about 200 degrees. No clear on-disc signatures of the CME are visible in the presently available data. Therefore, we conclude that this was probably back-side event and as such this CME will not arrive to Earth.
