FORECAST (06 FEBRUARY - 12 FEBRUARY) Solar: R2-R3 level solar activity is expected over 06-09 Feb to to AR4366. After this region leaves the solar disk R0-R1 level solar activity is expected over 10-12 Feb. Geomagnetic: G0 conditions are expected for most of the week, with a chance of G1 on 07-Feb due to a combination of coronal hole high speed wind stream effects and a possible glancing CME impact. Frequencies: MUFs are expected to be near predicted monthly values to enhanced by 15-30% throughout the week. Shortwave fadeouts are probable.
