During the last 24 hours, solar wind parameters, measured by the ACE spacecraft, were indicative of background solar wind conditions until 07:45 UTC on August 15, when a sudden impulse occurred due to the arrival of a co-rotating interaction region (CIR) ahead of a
A G1-Minor geomagnetic storm is in progress as a result of coronal hole high speed stream (CH HSS) buffeting Earth's magnetic field.Effects from the CH HSS are expected to continue disrupting the solar wind environment for the rest of the July 13.By July 14,
A new model of the Sun’s solar cycle is producing unprecedentedly accurate predictions of irregularities within the Sun’s 11-year heartbeat. Predictions from the model suggest that solar activity will fall by 60% during the 2030s to conditions last seen
During the late UTC hours of July 10, 2015, coronal hole high speed stream (CH HSS) hit Earth's magnetic field causing enhanced geomagnetic activity.Geomagnetic K-index of 5 threshold (G1-Minor geomagnetic storm) was first reached at 22:44 UTC. Area of impact was pr
Beta-gamma classified Region 2381 exhibited rapid growth over the past 24 hours (by 12:30 UtC today) and produced a moderately strong M1.0 solar flare at 08:44 UTC on July 6, 2015. The event started at 08:24 and ended at 08:59 UTC. There were no radio signatures that wo
During the last 24 hours, solar wind parameters reflected an enhanced solar wind environment due to the onset of a co-rotating interaction region (CIR) in advance of a negative polarity coronal hole high speed stream (CH HSS). Solar wind speed increased from initial va
Moderately strong solar flare reaching M1.5 at its peak time erupted at 12:53 UTC on July 3, 2015. The event started at 12:47 and ended at 12:53 UTC.The source was Region 2378, which rotated into the southwest quadrant yesterday producing innumerous C-class solar flares
Region 2371, the source of 4 Earth-directed Coronal Mass Ejections (CMEs) over the past couple of days, erupted with long duration M7.9 solar flare (R2-Moderate) at 08:16 UTC on June 25, 2015. The event started at 08:02 and ended at 09:05 UTC. A Type II (estimated veloc
Coronal Mass Ejection (CME) produced by a long duration M6.5 solar flare on June 22 appears to have arrived at 13:00 UTC on June 24.Bt increased to 15nT and solar wind velocities increased to over 700 km/s at the time. Bz, however, remained largely positive and the over
Three Coronal Mass Ejections (CMEs) produced on June 18, 19 and 21 have now all arrived at our planet and their combined effects caused G4-Strong geomagnetic storm on June 22, 2015. Two of the three CMEs were produced by Region 2371, one of the biggest regions of the cu
