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,
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
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
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
Coronal Mass Ejections (CMEs) from June 18, 19 and 21 have significantly increased chances for G3-Strong geomagnetic storms on June 22, 2015. Two of the three CMEs were produced by Region 2371, one of the biggest regions of the current solar cycle, which is currently di
Filament eruption in the SSE quadrant of the Sun produced a partial-halo Coronal Mass Ejection (CME) first observed in coronagraph imagery near 08:45 UTC on June 19 (above). WSA-Enlil model suggests a glancing blow early on June 23. Beta-Gamma-Delta classified…
Solar activity has increased to moderate levels during last 24 hours with an impulsive M1.0 solar flare (R1-Minor) at 08:55 UTC on June 11, 2015. The source was an area of enhanced emission on the Sun's east limb.Current SDO imagery reveals a cluster of sunspots
