Сонячно-активні області та спалахи

Solar flaring activity was low but frequent during the last 24 hours. The largest flare was an C5.7 flare, peaking at 00:09 on July 09, associated with NOAA AR 3366 (beta class). NOAA AR 3361 (beta-delta class) is currently the largest and most complex active region on the visible solar disc but produced only low level C-class flares in the last 24 hours. Low flaring activity was also produced by NOAA AR 3355 (alpha class), NOAA AR 3359 (beta class), NOAA AR 3363 (beta class), and by NOAA AR 3364 (alpha class). Other regions on the disc did not show any significant flaring activity. The solar flaring activity is expected to be at low levels over the next 24 hours with C-class flares likely and M-class flares possible.

Корональні викиди маси

No Earth-directed Coronal Mass Ejections (CME) were observed in the SOHO/LASCO coronograph images over the past 24 hours.

Сонячний вітер

Over the past 24 hours the solar wind parameters (ACE and DSCOVR) were slightly elevated. The solar wind speed ranged between 480 km/s and 520 km/s. The total interplanetary magnetic field varied between 3 and 7 nT. The southward component of the interplanetary magnetic field fluctuated between -3 nT and 6 nT. Solar wind parameters are expected to be slightly elevated over the next 24 hours due to the positive polarity CH HSS influence.

Геомагнетизм

During last 24 hours the geomagnetic conditions were quiet globally (NOAA KP 0-1). Locally quiet to unsettled conditions were observed over Belgium (K-Bel=1-3). Geomagnetic conditions are expected at quiet to unsettled levels during next days, due to HSS influence.

Рівні потоку протонів

The greater than 10 MeV proton was at the nominal levels in the past 24 hours. The proton flux is expected to remain below 10 pfu threshold over the next day, with a small chance that a particle event occurs in association with an X-class flare or a coronal mass ejection.

Потоки електронів на геостаціонарній орбіті

The greater than 2 MeV electron flux was below the 1000 pfu threshold. It is expected to remain below the threshold for the next 24 hours. The 24-hour electron fluence was at normal to moderate levels for the past 24 hours and it is expected to remain at these levels for the next 24 hours.
