Official Space Weather Advisory issued by NOAA Space Weather Prediction Center Boulder, Colorado, USA SPACE WEATHER ADVISORY OUTLOOK #17-42 2017 October 15 at 9:44 p.m. MDT (2017 October 16 0344 UTC) **** SPACE WEATHER OUTLOOK **** Summary For October 9-15 G1 (Minor) geomagnetic storm levels were observed on 11-15 October and G2 (Moderate) geomagnetic storm levels were observed on 13 October due to coronal hole high speed stream effects. Outlook For October 16-22 There is a chance for G1 (Minor) geomagnetic storm levels on 18-19 October due to coronal hole high speed stream effects. Data used to provide space weather services are contributed by NOAA, USAF, NASA, NSF, USGS, the International Space Environment Services and other observatories, universities, and institutions.
