Datum: Sun, 15 Mar 2015 12:06:06 GMT Od: Solar Influences Data analysis Center PRESTO ALERT :Issued: 2015 Mar 15 1205 UTC :Product: documentation at http://www.sidc.be/products/presto #--------------------------------------------------------------------# # FAST WARNING 'PRESTO' MESSAGE from the SIDC (RWC-Belgium) # #--------------------------------------------------------------------# A partial halo coronal mass ejection (CME) was reported by CACTus and first seen in LASCO/C2 images at 02:00UT on 15-Mar-2015. This CME was related to a C9.1 flare from NOAA 2297 peaking at 02:13UT. The related CME had a plane of the sky speed of 712 km/s, and a width of 160 degrees. The bulk of the CME is directed away from Earth to the West, but a glancing blow can not be ruled out based on current imagery. The CME is estimated to arrive at Earth on 16 March at 18:00UT (+/- 12 hours). #--------------------------------------------------------------------# # Solar Influences Data analysis Center - RWC Belgium # # Royal Observatory of Belgium # # Fax : 32 (0) 2 373 0 224 # # Tel.: 32 (0) 2 373 0 491 # # # # For more information, see http://www.sidc.be.

Around 4:04UT solar wind speed jumped abruptly from around 410 km/s to over 500 km/s. The total magnetic field increased from in the 8-10 nT range to the 24-28 nT range with Bz pronounced positive around the time of the jump. Also temperature and density increased although the density changed less abrupt and less pronounced. The total magnetic field meanwhile decreased to current levels of around 20 nT, while Bz became negative over the period with a negative peak of under -22nT around 5:30UT. Some rotation in the magnetic field phi angle was also visible. Local geomagnetic conditions remained quiet (K=2), but minor storm levels were recorded by NOAA Kp (K=5). The event is probably related to an earlier than expected arrival of the March 11 CME. #--------------------------------------------------------------------# # Solar Influences Data analysis Center - RWC Belgium # # Royal Observatory of Belgium # # Fax : 32 (0) 2 373 0 224 # # Tel.: 32 (0) 2 373 0 491 # # # # For more information, see http://www.sidc.be.

During the hours before sunrise on St. Patrick's Day, bright green skies appeared over multiple US states including Wisconsin, Washington, Minnesota, and the Dakotas.
