After Active Region 2567, the source of 7 M-class and numerous C-class solar flares between July 21 and 24, rotated away from the visible disk, our Earth facing Sun is again spotless. This is the third 'spotless Sun' since June 3, and although it is a…
Three strong solar flares erupted from Active Region 2567 early on July 23, 2016 – M5.0, M7.6, and M5.5. A Coronal Mass Ejection (CME) was produced during the third one, however, this region is not in a position to produce Earth-directed CMEs. The first flare…
After more than 3 months without any significant solar flare, our sun produced two consecutive M-class flares early on July 21, 2016. The source was Active Region 2567 ('beta-gamma' / 'beta'), currently moving out of its geoeffective position….
A geomagnetic storm reaching G1 – Minor levels is currently in progress following the early arrival of July 17th Coronal Mass Ejection (CME). The interplanetary shockwave produced by the long duration C1 flare on July 17, initially expected to arrive early on July…
Although solar activity was at low levels on July 17, 2016, geoeffective Active Region 2567 ('beta-gamma') managed to produce a long duration C1 solar flare. The event peaked at 06:42 UTC, producing a faint, asymmetric halo Coronal Mass Ejection (CME)….
Solar wind parameters reflected a brief enhancement associated with the arrival of a co-rotating interaction region (CIR) and subsequent negative polarity coronal hole high speed stream (CH HSS) late June 22, 2016. A gradual increase in solar wind speeds began after…
A co-rotating interaction region (CIR) – the transition zone between slow- and fast-moving streams of solar wind – has hit Earth's magnetic field on June 14, 2016, sparking geomagnetic storms. As of 19:55 UTC, a G2 – Moderate geomagnetic storm is in progress and…
A recurrent, negative polarity coronal hole high speed stream (CH HSS) has hit Earth's magnetic field causing geomagnetic storms on June 5, 2016. A G2 (Moderate) geomagnetic storm watch is currently in effect. This same CH HSS has affected Earth on May 8 with…
A G3 – Strong geomagnetic storm conditions were observed beginning 05:59 UTC on May 8, 2016. G2 – Moderate to G3 – Strong geomagnetic storm conditions are expected through the rest of the day and possibly into May 9 and 10. This activity is caused by a recurrent,…
Enhanced solar wind conditions have fueled elevated geomagnetic field activity early May 2, 2016. Geomagnetic storms reaching G2 – Moderate levels have been observed. Geomagnetic K-index of 5 (G1 – Minor geomagnetic storm) threshold was first reached at 00:37 UTC on…
