Previsor 1: During the period 09th-15th June, in the most of days, DESPITE the six activeregions on the solar disc, only one presented either a complex or relatively complex magnetic configuration, with a moderate potential to generate moderate to intense flares. On 9th June, a partial halo CME – probably associated to the C2 flare – was recorded. The arrival of this CME, at least in a glance blowing, is due on 12th June. Three low M-flares has been recorded on 1th, 13th and 14th June. Also, the coronal hole CH 672 crossed the central of the disc during 10th-11th June. For the week 16th-22nd June, one active region, out of six, present a relatively complex magnetic configuration and relatively low probability to generate moderate flares, and very low probability to generate intense flares. An active region, recurrent from last solar rotation, is due to return to the visible disc on 15th-17th June.
INTERPLANETARY MEDIUM AND MAGNETOSPHERE
Previsor 2: The interplanetary magnetic field and plasma parameters show nominal values up to day 11. At the beginning of the day 12, it was observed a cross sector boundary with changes in the interplanetary field strength, density and temperature. On the day 14, solar wind speed was raised due to a CH HSS positioning on the solar disc, yet on the day 14 it was observed a reverse shock on the interplanetary magnetic field data.
Previsor 3: During the period the geomagnetic field was mostly quiet, with minor active in the auroral region throughout. The AE index was around 500 nT during the entire period, this increasing at the auroral activity contributed to the Kp index to be intensified and reached levels around 4 to 3. The Dst index oscillated around zero, being predominantly positive on Jun 12nd . The Embrace magnetometer data network measured on day 12 was compatible with a shock associated to the June 9th CME, however results from the instruments on board the ACE satellite, associated with this period, did not show clearly the CME passage.
Previsor 4: The equatorial and mid latitude ionosphere, in general, was quiet during the last period. The peak height of the F2 layer was raised between June 10th and 11st; 14th and 15th . The other ionospheric indices showed no significant variations, the same was observed at TEC map. It were observed bubbles in Cachoeira Paulista station during the night of 13 to 14 and waves throughout the week in Cariri and Cachoeira Paulista stations.
