Notes:

Generally a quiet week. Most of the sub-storm activity that is seen by satellites in the daytime when I am making these measurements, is occurring, of course, in the distant parts of the world where its night time.

We found the two 'real-time' magnetometer stations at Kiruna, Sweden system and Flinders very helpful in corroborating the data taken.
