07 Jul 08 Jul 09 Jul Activity R0 R0 R0 Fadeouts None expected None expected None expected 10.7cm/SSN 115/66 113/64 111/62 COMMENT: Solar activity on UT day 6-Jul was R0, with no solar flares. There are currently five numbered sunspot regions on the solar disk. AR 4127 (S22W58, beta), AR4130 (S14W10, beta) and AR4132 (S25W14, beta) have all shown some minor growth over the past day but overall all visible sunspots are small and not showing significant potential for solar flares. Solar activity is expected to be R0 over 7-9 Jul. No Earth directed CMEs were observed on UT day 6-Jul. S0 solar radiation storm conditions were observed on UT day 6-Jul. S0 solar radiation storm conditions are expected over 7-9 Jul. The solar wind environment was mildly disturbed on UT day 6-Jul due to ongoing coronal hole effects. The solar wind speed ranged from 379 to 472 km/s and is slowly declining. The peak total interplanetary field strength (IMF, Bt) was 12 nT and the north-south IMF component range (Bz) was +9 to -10 nT, with several periods of southward Bz. The solar wind is expected to slowly return to background levels over 7-9 Jul, possibly increasing by the end of the period due to another small coronal hole.
