Сонячно-активні області та спалахи

Solar flaring activity over the past 24 hours was at moderate levels, with one M-class flare. The largest flare was a M2.17-flare, with peak time 11:02 UTC on July 01 associated with NOAA AR 3730 (beta-gamma). There are currently 15 numbered active regions on the visible disk. Low flaring activity was also produced by NOAA AR 3724 (alfa), NOAA AR 3727 (beta), NOAA AR 3728 (beta), NOAA AR 3729 (beta- gamma), NOAA AR 3733 (alfa), NOAA AR 3734 (beta) in the last 24 hours. NOAA AR 3719 and NOAA AR 3720 have started to rotate over the west limb. All other regions were inactive and stable. The solar flaring activity is likely to be at moderate levels over the coming days with C-class flares expected and M-class flares likely and a small chance for a X-class flares.

Корональні викиди маси

A Coronal Mass Ejection (CME), was detected at 14:48 UTC on June 30, in LASCO C2 data. The CME is associated with an eruption seen in SDO/AIA 304 at 13:59 UTC. Further analysis is ongoing.

The solar wind speed varied within 450-600 km/s. The interplanetary magnetic field varied between 3 nT and 8 nT, with the Bz reaching a minimum value of -6 nT. The phi-angle was mainly in the positive sector (directed away from the Sun) with periods in the negative sector. The solar wind is may become perturbed late on July 02, due to the possible ICME arrival of a June 29 CME.

Геомагнетизм

Geomagnetic conditions were globally quiet to unsettled (Kp 1-3) with some active periods locally (K_Bel 1-4). Quiet to unsettled conditions are expected in the next 24 hours.

Рівні потоку протонів

Over the past 24 hours the greater than 10 MeV GOES proton flux was at background levels and is expected to remain so over the next days.

Потоки електронів на геостаціонарній орбіті

The greater than 2 MeV electron flux measured by GOES 16 was below the 1000 pfu threshold and is expected to remain so in the upcoming days. The 24h electron fluence was at nominal level and is expected to remain so in the next days.
