The solar activity was at very low levels with no significant flares recorded. The solar disk remains spotless and no significant flares are expected over the next 24 hours.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in the available coronagraph imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours, and is expected to remain so in the next 24 hours. The greater than 2 MeV electron flux was continuously recorded above the 10^3 pfu threshold over the past 24 hours, remaining greater than 10^4 pfu. The electron flux is expected to remain elevated over the next 24 hours.

Over the past 24 hours the solar wind conditions remained under the waning influence of the high-speed stream related to the positive-polarity coronal hole (CH82). The total interplanetary magnetic field, as recorded by ACE and DSCOVR, varied between 2 nT and 4 nT with a weak north-south component fluctuating in the range of -3 nT and 3 nT. In the past 24 hours the solar wind speed continued to decline varying between 580 km/s and 490 km/s. The solar wind conditions are expected to continue returning to background levels over the next 24 hours.

The geomagnetic conditions over the past 24 hours were mostly quiet to unsettled with maximum recorded Kp and K Dourbes indices equal to 3. Quiet to unsettled conditions are expected to continue over the next 24 hours. A new small-area negative-polarity coronal hole (CH83) has now formed on the western hemisphere close to the central meridian. As a result we might observe unsettled to active conditions after 2.5-3 days.
