Solar alert

Issued on 2023 Apr 10 1004 UTC

The in situ data show arrival of the shock wave at about 22:00 UT on April 09, followed by the magnetic structure that might be the ICME (to become clear when more data is available). The solar source of this CME is not completely clear. One of the possibility is a faint, wide CME observed first time in the SOHO/LASCO C2 field of view at 09:24 UT on April 06, above the East solar limb. The other possibility is that the source is a stealth CME with no clear on-disc signatures. The arrival of the shock wave induced unsettled geomagnetic conditions.
