Halo CME on 20021025 - SOHO/LASCO C3 Data |
COMMENTS: The CME took off from AR 0162 at N35W10. If this CME hits the earth by its front edge,
there are strong chances that it will produce an intense geomagnetic storm.
The CME missed the earth, therefore, no real measurements can be compared with the predictions.
- CME's Source Region is NOAA AR 0162 ; P0= 25.446328; Day of Year # 298
- CME Appeared at 6 Solar Radii on 20021025 at 1842 UT
- CME Arrived at 20 Solar Radii on 20021025 at 2130 UT
- CME's Projected Speed at 20R: 1174 km/sec
- Estimated Travel Time is 2.06427 +/- 0.25 days
- Estimated Time of Arrival is 20021027 at 2303 UT ( COMMENTS: )1
- Estimated Speed of Solar Wind at 1AU is 508 km/sec (km/sec)
- Estimated Direction of the Bz at the
Leading Edge of the Magnetic Cloud is SOUTHWARD ()
- Estimated Magnitude of the hourly averaged Bz at the
Leading Edge of a Magnetic Cloud is -14...-28 nT (nT)
