Detailed Information

Solar Activity

Solar activity was on the quiet level. No flare, CME nor solar radio burst were detected in the last 24 hours. Today's observation from SDO/HMI Intensitygram shows the spotless Sun. Based on STEREO EUVI/AIA195 observation, a new active region is predicted to appear from the east limb on the late of Monday (June, 11).

Based on today's condition, 

  • Solar activity on June 8, 2018, starting from 08:00 UT is predicted to be quiet. Valid for 24 hours.
  • Solar activity on June 9, 2018, starting from 08:00 UT is predicted to be quiet. Valid for 24 hours.
  • Solar activity on June 10, 2018, starting from 08:00 UT is predicted to be quiet. Valid for 24 hours.
  • Solar activity on June 11, 2018, starting from 08:00 UT is predicted to be quiet. Valid for 24 hours.

Geomagnetic Activity

Geomagnetic activity was on quiet level.

Today's geomagnetic activity was on quiet level. Solar wind speed was around 375 km/s. IMF was varied between -4 to +8 nT. Today's coronal holes at north and south pole are not geoeffective,  but the other one on the southern equator can be considered as geoeffective. The latest substorm has occured on June 8th, around 03 UT with intensity less than 500 nT and its duration was about 2 hours.

  • Quiet level is expected at 08:00 UT of 8th June to 07:59 UT of 9th June 2018.
  • Quiet level is expected at 08:00 UT of 9th June to 07:59 UT of 10th June 2018.
  • Quiet level is expected at 08:00 UT of 10th June to 07:59 UT of 11th June 2018.
  • Quiet level is expected at 08:00 UT of 11th June to 07:59 UT of 12th June 2018.

Ionosphere Activity

Ionosphere was in quiet condition.

There was no depression of foF2 lower than 30% of its median values. There was no increment of fmin more than 30% of its median values. There was Spread-F event at least 3,5 hours. The Sporadic-E occurred in day time with foEs value less than foF2. The W-index mean value was -2. S4 index value (condition of ionospheric scintillation) over Bandung was in quite condition with value less than 0.25.

  • The ionosphere activity is predicted to be quiet for 8 June 2018, 8:00 UT - 9 June 2018, 7:59 UT.
  • The ionosphere activity is predicted to be quiet for 9 June 2018, 8:00 UT - 10 June 2018, 7:59 UT.
  • The ionosphere activity is predicted to be quiet for 10 June 2018, 8:00 UT - 11 June 2018, 7:59 UT.
  • The ionosphere activity is predicted to be quiet for 11 June 2018, 8:00 UT - 12 June 2018, 7:59 UT.

Navigation

The Error positioning was slight based on W-index value -2.

  • The probability of error positioning for 8 June2018, 8:00 UT - 9 June 2018, 7:59 UT is slight during daytime and nighttime based on W-index value that going to be -2.
  • The probability of error positioning for 9 June 2018, 8:00 UT - 10 June 2018, 7:59 UT is slight during daytime and nighttime based on W-index value that going to be -2.
  • The probability of error positioning for 10 June 2018, 8:00 UT - 11 June 2018, 7:59 UT is medium during daytime and nighttime based on W-index value that going to be -3.
  • The probability of error positioning for 11 June 2018, 8:00 UT - 12 June 2018, 7:59 UT is medium during daytime and nighttime based on W-index value that going to be -3.

HF Radio Communication

  • The probability of MUF depression for 8 June2018, 8:00 UT - 9 June 2018, 7:59 UT is quiet due to previous and prediction of geomagnetic activity.
  • The probability of MUF depression for 9 June 2018, 8:00 UT - 10 June 2018, 7:59 UT is quiet due to previous and prediction of geomagnetic activity.
  • The probability of MUF depression for 10 June 2018, 8:00 UT - 11 June 2018, 7:59 UT is quiet due to previous and prediction of geomagnetic activity.
  • The probability of MUF depression for 11 June 2018, 8:00 UT - 12 June 2018, 7:59 UT is quiet due to previous and prediction of geomagnetic activity.
  • The probability of SWF for 8 June2018, 8:00 UT - 9 June 2018, 7:59 UT is quiet due to the prediction of solar flare activities.
  • The probability of SWF for 9 June 2018, 8:00 UT - 10 June 2018, 7:59 UT is quiet due to the prediction of solar flare activities.
  • The probability of SWF for 10 June 2018, 8:00 UT - 11 June 2018, 7:59 UT is quiet due to the prediction of solar flare activities.
  • The probability of SWF for 11 June 2018, 8:00 UT - 12 June 2018, 7:59 UT is quiet due to the prediction of solar flare activities.
