Prediction for CME (2019-05-13T16:09:00-CME-001)
CME Observed Time: 2019-05-13T16:09ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/14752/-1
CME Note: Signature is very weak and difficult to discern exact time. From Teresa Nieves-Chinchilla: Around ~21 hrs on the May 16, there is a monotonic change in the magnetic field direction that can be associated with a flux rope signature.
CME Shock Arrival Time: 2019-05-16T16:10Z

Max Kp: 3.0
Predicted Arrival Time: 2019-05-16T15:00Z (-12.0h, +12.0h)
Confidence that the CME will arrive: 90.0%

The chance for a C flare in the next 24 hours, especially from region 2741, is estimated at 40%. No Earth-directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours. The solar wind speed as registered by DSCOVR varied between about 400 and 460 km/s in the past 24 hours, with current values around 420 km/s. The Interplanetary Magnetic Field was directed predominantly away from the Sun, and its magnitude varied between about 2 and 10 nT, with current values around 6 nT. Bz was never below -5 nT for extended periods. Enhanced solar wind conditions are expected in the next days, with the expected arrival of the May 11, 12 and 13 CMEs. Quiet to unsettled geomagnetic conditions (K Dourbes between 1 and 3; NOAA Kp between 1 and 2) were registered in the past 24 hours. Active to moderate storm intervals (K Dourbes = 4-6) are possible on May 16 and 17, due to the expected arrival of the May 11, 12 and 13 CMEs. A return to quiet to unsettled geomagnetic levels is expected on May 18. TODAY'S ESTIMATED ISN : 014, BASED ON 22 STATIONS.

Rules of the Road: CCMC requests that users notify the CCMC, CME
model/technique developers and submitting forecasters/researchers before
performing event and validation studies with data from the CME Arrival
Time Scoreboard. It is recommended that such studies be performed with
the knowledge and collaboration of developers and submitting
forecasters/researchers.
