Solar flaring activity was at low levels over the past 24 hours. NOAA AR 2057 has been the most energetic, producing the largest flare of the period, a long duration C2.6-class flare, peaking at 24 July 07:31 UT. It is about to rotate off the visible solar disk. The flaring activity is expected to be at low levels over the next 24 hours.

A full halo coronal mass ejection was detected by the CACTus automated algorithm. Onset time was determined to be 23 July 18:48 UT, with an average speed about 1700 km/s. This is believed to mainly be a back-sided event. However, it cannot be excluded that a brightening seen in Lasco C2 23 July 19:48 UT and Stereo A 23 July 20:23 UT, with direction SE, may be associated with a filament eruption around AR 3059 on 23/7 19:03 UT. In that case, a shock arrival may arrive early 28 July. It is however also possible that there was a filament eruption from the non-visible solar disk causing this brightening, making this event unclear.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours. The proton flux is expected to remain at nominal levels for the next 24 hours. The greater than 2MeV electron flux was about the 1000 pfu threshold over the past 24 hours. It is expected be about threshold over the next 24 hours. The 24h electron fluence was at nominal levels over the past 24 hours. It is expected be at nominal to moderate levels over the next 24 hours.

The solar wind parameters reflect the waning influences of the high speed stream (HSS) and the ICME of the past days. Over the past 24 hours, the solar wind magnetic field values fluctuated between 1 and 7 nT, while Bz had values between -4 and 6nT. The solar wind speed was measured (DSCOVR) to be between 500 and 585 km/s. The interplanetary magnetic field phi angle was on the negative sector (towards the Sun). Over the next 24 hours, we are expecting the impact of those effects to decreased further.

Quiet to unsettled conditions were recorded over the past 24 hours (NOAA Kp and K Dourbes 3). Over next the 24 hours, quiet to unsettled conditions are expected.
