Isolated but intense geomagnetic activity is expected the next week

Solar activity experienced an increase in the past week as reflected by the rise in average daily sunspot numbers from 149.6 to 181.6. However, there was a peculiar decrease in average daily solar flux from 178 to 175. This is reported by SSP.

Throughout the week, a total of seven new sunspot groups emerged on specific dates. One sunspot group appeared on June 27, two on June 28, three on June 29, and an additional one on July 3.

Additionally, there was an increase observed in both the average daily planetary index, which rose from 10.3 to 15.6, and the average middle latitude A index, which increased from 10.1 to 11.6.

One significant event occurred on Friday, June 28, when a severe G4 class geomagnetic storm was caused by a Coronal Mass Ejection (CME). Measuring the impact, the middle latitude A index reached 32, while the planetary A index reached 59 - considerably higher than Alaska's college A index of 36.

Moving forward into the next week, we are anticipating mostly calm to unsettled conditions. However, there is a possibility of encountering more unsettled conditions, including isolated active events, around July 7 and 8. Similarly, towards the end of the forecast period, specifically Thursday, July 11, another period of unsettled activity is expected.
