International SUNday June 26th 2016

Report.............The day started cloudy and remained so for the bulk of the afternoon. Occasional patches of blue sky tempted members to break out the Ha scopes but as soon as equipment was set up the cloud obscured the sun again. Some radio astronomy measurements were taken. Consulting the Internet solar  reports showed low activity, a minimum of sunspots and small prominences on the solar limb. Blue sky was seen to the east of the AC for some time- we hope observers further into Yorkshire had better luck. Rain started at 16.15.
