Sentence examples for minimum geomagnetic activity from inspiring English sources

There is a minimum geomagnetic activity interval in cycle 22 (day 106, 1996, to day 23, 1998).

We call the reader's attention to the long delay between the sunspot minima and the geomagnetic activity minima.

Thus, the low solar magnetic fields, the lack of CMEs, and the midlatitude location of small coronal holes all contribute to the all-time minimum in the geomagnetic activity between 2008 and 2009.

However, the trough minimum position depends primarily on geomagnetic activity.

The trough minimum position depends primarily on geomagnetic activity, MLT, and the season.

The results showed that the trough minimum position depended primarily on the geomagnetic activity, MLT, and the season.

Figure 7 shows the solar activity variation of trough depth (upper panels), background TEC (middle panels), and TEC value at the trough minimum (lower panels) at a low geomagnetic activity level.

We need to continuously watch geomagnetic activity in declining-minimum phase of cycle 24 for further understanding of this weak cycle.

The simulation revealed a dominant role of the extreme solar EUV decrease in the last solar minimum together with minor contribution from lower geomagnetic activity and very minor contribution from anthropogenic increase of CO2.

It was observed that during solar maximum, 36% and 28% of interplanetary shocks were followed by intense (Dst ⩽ −100 nT) and moderate (−50 ⩽ Dst < −100 nT) geomagnetic activity, whereas during solar minimum 13%and33%3% of the shocks were followed by intense and moderate geomagnetic activity.

As shown, the trough minimum position moves to a lower latitude as geomagnetic activity increases.
