Very strong M7.3 earthquake hits Venezuela at intermediate depth
A very strong earthquake registered by the USGS as M7.3 hit near the coast of Sucre, Venezuela at 21:31 UTC on August 21, 2018. The agency is reporting a depth of 123.2 km (76.5 km). EMSC is reporting M7.3 at a depth of 112 km (69.6 miles). According to the USGS, the epicenter was located  20.9 km (13.0 miles) NNW of Yaguaraparo, 38.4 km (23.9 miles) ENE of Carúpano (population 112 082), 69.4 km (43.1 miles) WNW of Güiria (population 40 000), 107.6 km (66.9 miles) ESE Porlamar (population 87 120) and 109.1 km (67.8 miles) ESE of La Asunción (population  35 084), Venezuela. There are 560 000 people living within 100 km (62 miles). Based on all available data, there is no tsunami threat, PTWC said. Some 52 000 people are estimated to have felt very strong shaking, 2 089 000 strong, 2 587 000 moderate and 3 928 000 light. Buildings were evacuated in the capital Caracas and people fled homes. Shaking was felt as far away as …

Solar filament eruption, possible glancing blow on November 29

Solar filament eruption, possible glancing blow on November 29

A solar filament was observed lifting off the Sun's northeastern quadrant beginning at approximately 04:45 UTC on November 25, 2017.
An associated weak Coronal Mass Ejection (CME) was observed in SOHO/LASCO C2 and C3 imagery and the analysis shows a potential glancing blow arriving at Earth on November 29.

Another filament is anchored in the southwest filament and is rotating away from the geoeffective position.

Solar activity was at very low levels today and is expected to remain like that, with just a slight chance for C-class flares over the next three days
There is only one numbered sunspot region on the Earth side of the Sun-AR 2689. Although this region showed signs of growth over the past 24 hours, it lacked significant flare activity.
The greater than 2 MeV electron flux was at normal to moderate levels over the past 24 hours, with a peak flux of 309 pfu observed at 15:05 UTC on November 25.
Solar wind parameters are currently at ambient background conditions and expected to become enhanced on November 27 and 28 as a negative polarity coronal hole high-speed stream (CH HSS) becomes geoeffective.
Unsettled to active geomagnetic field levels are expected on November 27 and 28 due to the onset of negative polarity CH HSS.
