The background X-ray radiation level has increased to just below the C-level. Catania 6 (NOAA AR 1773) has grown a little. It has the potential to flare in the C-level. The knot of Catania sunspot groups 2, 3, 5, 7 (NOAA AR 1772, 1770, 1774 and 1775 respectively) and 8 has a large potential to flare in the C-level. There is a chance for M-flaring activity, below 50% however. A large coronal hole is visible on the east side of the central meridian in the northern hemisphere. The lower boundary extends to about 25°N. The fast solar wind emanating from this hole can possibly reach the earth in 3-4 days.
