04 Jul 05 Jul 06 Jul Activity Low to moderate Low to moderate Low to moderate Fadeouts Possible Possible Possible 10.7cm/SSN 112/63 112/63 115/66 COMMENT: Solar flare activity was moderate during 3 Jul UT. AR 2378 (S17E56) produced the largest flare of the day, an M1.5 event peaking at 12:51 UT. AR 2378 also produced five C class flares. This region may produce another M class flare during the next 3 days. The CME recorded leaving the NE limb late during 2 Jul will not be geoeffective. There was a filament eruption in the SW quadrant during 3 UT on 3 Jul. No associated CME was observed. Coronal Hole 675 has rotated into the Western Hemisphere. Fast solar wind is expected to arrive later today and drive unsettled to active geomagnetic conditions during 5 Jul. The solar wind speed decreased from about 350 km/s to 300 km/s during 3 Jul. The magnitude of the IMF was about 4 nT and the Bz component fluctuated mostly in the range -2 nT to +2 nT.
