30 Sep 01 Oct 02 Oct Activity Moderate Moderate Moderate Fadeouts Possible Possible Possible 10.7cm/SSN 185/138 185/138 175/129 COMMENT: The 10.7 cm solar flux was 175 on Sep 29 and is expected to rise to a local maximum during the next 2-3 days before slowly declining again. Solar X-ray flare activity was low during Sep 29. AR 2177 produced the largest flare of the day, a C5.4 event peaking at 05:54 UT. Several solar active regions have the potential to release an M class flare today and there is a small chance of an X ray flare. Solar activity is expected to be moderate during Sep 30 to Oct 1. GONG H alpha images show two 20-degrees long filaments located in the western hemisphere. They are stable at the time of this report. There are also no Earthward directed CMEs. The solar wind speed declined to about 350 km/s and the magnitude of the IMF is about 6 nT. The Bz component has been fluctuating in the approximate range -5 nT to +5 nT.

Solar Activity levels are explained in the IPS Solar Terrestrial Glossary.
