The solar activity was quiet over the past 24 hours, with the GOES X-ray flux remaining below B-level. The bipolar sunspot group (Catania sunspot group 1, NOAA-AR 2827) decayed slowly. The bipolar sunspot region (Catania sunspot group 2, NOAA-AR 2829) continued to grow but did not produce any significant flare. The solar activity is expected to remain quiet for the next 24 hours with a small probability to produce C-class flare.

No Earth directed Coronal Mass Ejection (CME) has been detected in the available coronagraph imagery.

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to remain so for the next 24 hours. The greater than 2 MeV electron flux was below the 1000 pfu threshold in the past 24 hours and is expected to remain so during the next 24 hours. The 24h electron fluence was at normal levels in the last 24 hours and is expected to stay at normal levels for the next 24 hours.

The solar wind parameters (as observed by ACE and DSCOVR) showed an ambient mostly background and slow solar wind speed regime. The solar wind speed ranged between 310 km/s to 438 km/s. The interplanetary magnetic field magnitude was below 6.6 nT, and Bz components varied between -4.5 nT and 4.4 nT. An equatorial coronal hole in the south hemisphere with positive magnetic polarity has reached the central meridian on June 04. The high- speed stream associated with this equatorial coronal hole may enhance the solar wind condition in about three days from now.

The geomagnetic conditions were quiet over the past 24 hours and is expected to remain quiet for the next 24-hour periods.
