There are currently 9 sunspot groups visible, with NOAA 2104 and 2109 the largest and magnetically most complex regions. Only 1 C-class flare was recorded. This C2.4 flare peaked at 05:37UT and had its source in NOAA 2109. A long filament near the west limb became unstable and mostly disappeared overnight (3-4 July), however no obvious CME was observed. Some subflaring activity in the long filament near NOAA 2106 was observed around 09:30UT.
C-class flares are expected, with a chance on a strong flare from especially NOAA 2104 and 2109.
Solar wind speed remained fairly constant around 350 km/s. Bz was mostly negative between 21:00 and 08:00UT, and positive for the rest of the period. Its value varied between -5 and +4 nT. Quiet geomagnetic conditions were observed and are expected to remain so.

No C-class (or higher) flares were observed over the last 24 hours, while the x-ray background flux remained close to the C1-level. There are currently 9 sunspot groups visible on the solar disk, with NOAA 2104 and 2107 being the largest and both having a magnetic delta. NOAA 2106 quieted down after its M1-flare from yesterday noon, part of the filament still being present. The CME associated to this flare was mainly directed to the north. It will deliver at most a glancing blow late on 5 July, with little influence on the geomagnetic field expected. Active regions are just behind the east limb, and 2 long filaments are present on the solar disk (one in the southwest quadrant, another about 20 degrees west of NOAA 2107).
C-class flares are expected, with a chance on an isolated M-class flare. Solar wind speed decreased from 350 to 300 km/s, while Bz varied between -2 and +2 nT. Geomagnetic conditions were quiet and expected to remain so.

The ARs rotating over the east limb into the visible disk are producing most of the activity at present. The strongest flare was a C4.9 with peak at 11:52 UT, originating in NOAA AR 2104 (no Catania number). This AR, and NOAA AR 2102 (no Catania number), will most likely produce more C-class and probably M-class flares.With solar wind speeds around 350 km/s and interplanetary magnetic field with a magnitude of 3 nT geomagnetic conditions are quiet and expected to remain so.

No C-class flares in past 24h. NOAA ARs 2093, 2096 and 2097 could produce C-class flares in the coming hours. Geomagnetic conditions are quiet and expected to remain so until the arrival of an ICME expected on June 24 (corresponding to the CME on June 20), active to minor storm levels are expected.

Only one C-class flare took place in the past 24 hours: the C1.0 flarepeaking at 19:46 UT on June 21 in the Catania sunspot group 89 (that, together with the Catania sunspot group 90, constitutes the NOAA AR 2093). It was accompanied by small coronal dimmings and a post-eruption arcade, but the associated CME (if any) was weak and narrow, so we do not expect it to arrive at the Earth. We expect flaring at the C-level in the Catania sunspot group 89 and in an unnumbered sunspot group that appeared from behind the east limb yesterday evening. The Earth is currently inside a slow (around 370 km/s) solar wind flow with average (around 5 nT) interplanetary magnetic field magnitude. The geomagnetic conditions are quiet and are expected to remain so until June 24, when we expect the arrival of the ICME associated with the partial halo CME on June 20, which may result in active to minor storm conditions.

During the past 24 hours, only three C-class flares were reported, and all of them were weak (below C2 level). NOAA AR 2089 has the beta-gamma configuration of its photospheric magnetic field, but it produced only one
C-class flare during this period. We expect flaring activity to continue on the C-level, in particular in NOAA ARs 2087 and 2089, as well as in the newly emerged NOAA AR 2095. Yesterday evening the interplanetary magnetic field (IMF) magnitude reached 10 nT, with intervals of negative north-south IMF component. Active to minor storm geomagnetic conditions were reported (Kp = 5 by NOAA, K = 5 by IZMIRAN, K = 4 by Dourbes). Currently the Earth is inside a slow (around 440 km/s) solar wind flow with average (around 5 nT) IMF magnitude. The geomagnetic conditions are quiet and are expected to remain so.

One single C-class flare was observed with peak at 10:24 UT on June 6, originating from Catania sunspot group 69 (NOAA AR 2080). This sunspot region has increased in size and evolved to a region with beta-gamma configuration. Also Catania sunspot group 71 (NOAA AR 2082) has grown, while all other regions remained stable. Analysis of the CME mentioned in yesterday’s ursigram (with first measurement at 15:24 UT on 4 June) revealed no geoeffective part of this CME is expected to arrive. Flaring activity is expected to be at C-class level, with a slight chance for an M-class flare. No geoeffective CMEs were observed.Currently we are experiencing stable solar wind conditions with a solar wind speed around 350 km/s and a magnitude of the interplanetary magnetic field near 5 nT. Quiet geomagnetic conditions were observed and are expected to continue until the arrival of a high speed stream. This might result in time slots with unsettled to active geomagnetic conditions from later today (UT time) on.

Six sunspot regions are visible at the front side of the solar disk. The background level of the X-ray flux measured by GOES is at B-class level. No solar flares were observed during the past 24 hours. LASCO/C2 observed at 8:36 UT a CME, which is associated with a backsided event. No Earth-directed CMEs were detected. C-class flares are expected for the next 48 hours, with NOAA ARs 2077 and 2079 as strongest source candidates. We are currently experiencing slow solar wind conditions, with a speed between 260
and 300 km/s. The magnitude of the interplanetary magnetic field is stable near 5 nT, with a fluctuating Bz component between -5 and +5 nT. The geomagnetic conditions were quiet. A small coronal hole that passed the central meridian on 29 May can still influence the geomagnetic field within the next 24 hours.
Geomagnetic conditions are expected to remain quiet, though locally a brief active episode is possible.

There are currently 5 sunspot regions visible. Three C-class flares were recorded over the last 24 hours. Near the time of its disappearance from the solar surface, active region NOAA 2076 produced a C1-flare peaking at 15:56UT. The strongest event of the period was a C2-flare in NOAA 2079 peaking at 01:37UT. The associated CME was directed away from Earth. NOAA 2077 produced a C1-flare peaking at 11:53UT. Further C-class flaring is expected, in particular from sunspot regions NOAA 2077 and NOAA 2079.
Solar wind speed declined from about 350 to 300 km/s, Bz being mostly positive with maximum excursions to +8 nT. The geomagnetic field was quiet. A small coronal hole that passed the central meridian on 29 May can
influence the geomagnetic field as of 2 June.
Geomagnetic conditions are expected to remain quiet, though locally a brief active episode is possible.
