COMMENT: Solar wind speed increased to 420 km/s over the UT day 
due to a recurrent coronal hole. This hole is thin in solar longitude 
however, so effects should only last for a day or two. IMF Bz 
varied north and south at low magnitudes ,not inducive for merging 
with the geomagnetic field. Sunspot activity is minimal with 
AR1076 rotating off the disc and AR1078 providing a few B-class 
X-ray flares and type III radio bursts. The STEREO-B spacecraft 
has observed a prolonged Bz southwards period, estimated to meet 
Earth on 13-14th June and probably associated with a solar sector 
boundary predicted in models.
