Coronal Mass Ejection

Event ID: 2023-01-31T13:23:00-CME-001

  • Start: 01/31/2023 13:23:00 UTC
  • Catalog: M2M_CATALOG
  • Location:
  • Region Number:

This CME is very faint, but visible to the south in SOHO LASCO C3 and to the S/SE in STEREO A COR2. The source is likely far-sided as there are no clear source signatures on the Earth-facing disk.

A. NOAA Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 3 (below NOAA
Scale levels).
The greatest expected 3 hr Kp for Feb 01-Feb 03 2023 is 3.00 (below NOAA
Scale levels).

Rationale: No G1 (Minor) or greater geomagnetic storms are expected.  No
significant transient or recurrent solar wind features are forecast.

B. NOAA Solar Radiation Activity Observation and Forecast

Solar radiation, as observed by NOAA GOES-18 over the past 24 hours, was
below S-scale storm level thresholds.

Solar Radiation Storm Forecast for Feb 01-Feb 03 2023

              Feb 01  Feb 02  Feb 03
S1 or greater    1%      1%      1%

Rationale: No S1 (Minor) or greater solar radiation storms are expected.
No significant active region activity favorable for radiation storm
production is forecast.

C. NOAA Radio Blackout Activity and Forecast

No radio blackouts were observed over the past 24 hours.

Radio Blackout Forecast for Feb 01-Feb 03 2023

              Feb 01        Feb 02        Feb 03

R3 or greater    5%            5%            5%

Rationale: There is a slight chance for R1-R2 (Minor-Moderate) radio
blackouts through 03 Feb, and a lesser chance for R3 (Strong) or greater
radio blackouts.
