The visible disc is spotless. No Earthward directed CMEs were observed in the available coronagraph images. Very Low levels of solar activity, with a chance of isolated C-class flares, are expected for the next three UT days, 01-03 June. During UT day 31 May, the solar wind speed varied between 370-430 km/s. The total IMF (Bt) varied between 2-6 nT and the north-south IMF component (Bz) varied between +4/-4 nT.

There are two numbered active regions on the visible disc, AR 2764 and AR 2765. Currently AR 2764 has no sunspots. No Earthward directed CMEs were observed in the available coronagraph images. Very low levels of solar activity with a little chance of isolated C-class flares are expected for the next three UT days, 05-07 June. During UT day 04 June, the solar wind speed varied in the range 310-350 km/s. The total IMF (Bt) varied between 0 nT and 5 nT, and the north-south IMF component (Bz) varied mostly in the range -5/+3 nT. The solar wind speed is expected to stay mostly near its background level during UT days 05-07 June, with possible moderate enhancements. ----------------------------------------------------------- 2A.

There is currently one active region with sunspots on the visible disc, AR 2765(S23E19) produced few B class flares with the largest being a B6.4 flare at 07/2146UT. Noted an unstable filament around AR 2765, monitored as it approaches centre disk. No Earthward directed CMEs were observed in the available coronagraph images up to 07/2225UT. Very low levels of solar activity with a chance of isolated C-class flares are expected for the next three UT days, 08-10 June. The solar wind speed remained near its nominal level until 07/1400 UT after which it increased, currently around 480 Km/s. At the same time the IMF conditions observed a minor perturbation, the total IMF (Bt) reached 13 nT ad the north-south IMF component (Bz) -10 nT, respectively due to the influence of a high speed solar wind stream from a coronal hole. Solar wind speeds are expected to remain enhanced over the next 24-36 hours due to continued coronal hole effects. ----------------------------------------------------------- 2A.

SOLAR FORECAST 17 Jun 18 Jun 19 Jun Activity Very low Very low Very low Fadeouts None expected None expected None expected 10.7cm/SSN 70/5 70/5 70/5 COMMENT: Solar activity was Very Low on UT day 16 June. Very Low solar activity is expected for the next three UT days, 17-19 June. There are currently no numbered active regions on the solar disk as active region 2765 has rotated around the western limb. No returning regions are expected. No Earthward directed CMEs were observed in the available coronagraph images. During the last 24 hours, the solar wind speed, as measured by DSCOVR, increased after 16/0800 UT from around 320 km/s to between 400 to 500 km/s. However, the solar wind speed, as measured by ACE, only increased to between 340 to 380 km/s. The phi angle rotated from positive to negative at the same time, possibly due to a solar sector boundary crossing (SSBC). The IMF only experienced a minor increase. The total IMF (Bt) varied in the range 1-6 nT and the north-south IMF component (Bz) range was -4/+4 nT. Solar wind conditions are expected to have moderate enhancements on UT days 17 to 18 June due to coronal hole effects, returning to background levels on UT day 19 June. ----------------------------------------------------------- 2A.

There are currently no numbered active regions on the visible solar disk. Very Low solar activity is expected for the next three UT days, 24-26 June. GONG Halpha imagery showed a filament structure in the NW quadrant, it is monitored for any lift off. A slow narrow CME was observed in STEREO imagery staring 22/1639UT but very faint in LASCO imagery. This event will be further analysed to determine if it has any earth directed component. No other Earthward directed CMEs were observed in the available coronagraph images. During UT day 23 June, the solar wind speed remained at nominal levels, near 300 km/s. The total IMF (Bt) varied between 2-5 nT and the north-south IMF component (Bz) varied mostly between +/- 2 nT with a southward excursion up to -5 nT around 23/2000UT. The solar wind speed is expected to remain mostly near its background levels for the next three days, 24-26 June, although some slight enhancements may be observed due to weak coronal hole. ----------------------------------------------------------- 2A.

SOLAR FORECAST 29 Jun 30 Jun 01 Jul Activity Very low Very low Very low Fadeouts None expected None expected None expected 10.7cm/SSN 68/2 68/2 68/2 COMMENT: Solar activity was very low on UT day 28 June. There are currently no numbered regions on the visible solar disc. Very low solar activity is expected for the next three UT days, 29 June to 01 July. No Earthward directed CMEs were observed in the available coronagraph images. During UT day 28 June, the solar wind speed was decreasing from 380 km/s to 320 km/s, currently near 330 km/s. The total IMF (Bt) varied between 3 and 5 nT and the north-south IMF component (Bz) varied in the range +2/-4 nT. During the next three UT days, 29 June to 01 July, the solar wind speed is expected to vary between its background levels and moderately enhanced values; mild to moderate enhancements are possible due to minor coronal hole effects. ----------------------------------------------------------- 2A.

Mostly quiet conditions with isolated unsettled periods were observed in the Antarctic region. Global geomagnetic activity is expected to be mostly quiet for the next three UT days, 29 June to 01 July, with a chance of isolated unsettled periods due to week coronal hole effects. ----------------------------------------------------------- 3A.

There are currently no numbered regions on the visible solar disc. Very low solar activity is expected for the next three UT days, 30 June to 02 July. No Earthward directed CMEs were observed in the available coronagraph images. During UT day 29 June, the solar wind speed varied between 320 km/s and 360 km/s, the total IMF (Bt) varied between 2 and 4 nT and the north-south IMF component (Bz) varied in the range +3/-3 nT. The solar wind particle density varied between 3 ppcc and 6 ppcc during this time. During the next three UT days, 30 June to 02 July, the solar wind speed is expected to vary between its background levels and slightly enhanced values due to possible minor coronal hole effects. ----------------------------------------------------------- 2A.
