Additional Comments

The Bz component of the interplanetary magnetic field has dived into the negative values and remained so for the past 11 hours. This is a result of the connection with a slow-moving coronal mass ejection that erupted from the Sun a few days prior, which is embedded in the background solar wind speed. There is a small chance of coronal hole influence at the end of the third forecast period from a small, equatorially positioned coronal hole that may lead to unsettled conditions. Solar wind speed remains at background level and this is expected to continue for the next three forecast periods.
In the last 24 hours, further solar flares were emitted from the two numbered active regions of the Sun, and more are expected. They are not considered to cause any impact on the geomagnetic conditions so far.
