Geomagnetic storm reaching G2-Moderate levels has been observed on August 27, 2015, mostly due to effects of August 22 CME that arrived late on August 25. This activity is expected to slightly wane throughout the day, but active levels are again expected later in the da
New activity/unrest was observed at 5 volcanoes from August 19 – 25, 2015. During the same period, ongoing activity was observed at 17 volcanoes. New activity/unrest: Aira, Kyushu (Japan) | Cleveland, Chuginadak Island (USA) | Cotopaxi, Ecuador | Nevado del Ruiz,
A moderately strong solar flare measuring M2.9 at its peak time erupted from Region 2403 on August 27, 2015. This was a long duration flare; the event started at 04:48, peaked at 05:44 and ended at 06:03 UTC.There were no associated radio signatures that would suggest a
At 07:33 UTC on August 24, Active Region 2403 produced its 7th M-class solar flare, and strongest so far, since it rotated onto the Earth side of the Sun. Today's event was impulsive in nature, it started at 07:26, peaked at 07:33 as M5.6 and ended at 07:35
A co-rotating interaction region (CIR) ahead of a series of positive polarity coronal hole high speed streams (CH HSS) is causing elevated geomagnetic field levels on Sunday, August 23, 2015.A further enhancement is expected early to midday August 24 with the arrival

Region 2403 erupted with its fourth M-class solar flare at 06:49 UTC on August 22, 2015. The latest event started at 06:39, peaked at 06:49 as M1.2, and ended at 06:59 UTC. Radio signatures indicate a Coronal Mass Ejection (CME) was produced.A Type II Radio Emission wit
At 20:34 UTC on August 21, Region 2403 erupted with its third M-class solar flare of the day. The event started at 19:10, peaked at 20:34 as M1.1 and ended at 20:50 UTC.This was a long duration event. However, there were no recorded radio signatures that would suggest a
Typhoon "Goni" is crawling north of Philippines today and hitting hard the island of Luzon. At least 5 people were killed, and 2 are missing after heavy rains triggered floods and numerous landslides. Goni will pass east of Taiwan on August 22 and 23, and
A second M-class solar flare of the day erupted from Region 2403 at 09:48 UTC on August 21, 2015. The event started at 09:34, peaked at 09:48 as M1.4 solar flare, and ended at 10:07 UTC. Radio signatures suggest a Coronal Mass Ejection (CME) was produced. These are the
Region 2403, located in the southeast quadrant, erupted with moderately strong M1.2 solar flare at 02:18 UTC on August 21, 2015. The event started at 01:56, peaked at 02:18 and ended at 02:37 UTC.There were no radio signatures that would suggest a Coronal Mass Ejection
