Highlights of Solar and Geomagnetic Activity
24 - 30 June 2024

Solar activity reached moderate levels on 24-25 Jun. The largest
flare was an M1.8 flare from Region 3712 (S26 L=170,
class/area=Eao/220) at 24/0417 UTC. Other M1 flares were observed
from Regions 3713 (S14 L=153, class/area=Ekc/360), 3720 (S06 L=54,
class/area=Dai/150), and 3723 (S19 L=08, class/area=Fai/210). Solar
activity was at low levels for 26-30 Jun, with only C-class flares
observed. Other notable activity included an approximately 35 degree
filament erupted late on 24 Jun, centered near S19W58. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at
normal to moderate levels. 

Geomagnetic field activity was reached G4 (Severe) storm levels on
28 Jun due to the arrival of a CME that lifted off the Sun on 24
Jun. Total field strengeth reached 30 nT and the Bz component
reached -22 nT. Solar wind speeds increased steadily from near 300
km/s to approximately 490 km/s. Active levels were reached early on
29 Jun due to continued CME influences. Quiet to unsettled levels
were observed on 24-27 Jun, and 30 Jun. 

Forecast of Solar and Geomagnetic Activity
01 July - 27 July 2024

Solar activity is expected to be low levels, with occasional M-class
flares for the duration of the period. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at moderate levels from 01-27 Jul. 

Geomagnetic field activity is expected to be at unsettled to active
levels on 01-03 Jul due to possible glancing influences from
multiple CMEs. Unsettled to active levels are expected on 14-16 Jul
due to influence from a recurrent, positive polarity coronal hole
high speed stream (CH HSS). Quiet to unsettled levels are expected
on 05-13 Jul and 17-27 Jul.
