Prediction for CME (2019-05-07T04:42:00-CME-001)
CME Observed Time: 2019-05-07T04:42ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/14725/-1
CME Note: This is an extremely faint CME and a possible partial halo seen going to the South East in C3. There could be several potential associated eruptions associated with it, with no definite clarity. Now that C2 images are available, it seems that most probably the CME is associated with a slow lift off of a long N-S oriented filament north from the AR 2740. The CME has an unusually-shaped front (as seen in STA and in difference C3 imagery).

Prediction Method Note:
:Issued: 2019 May 07 2138 UTC :Product: documentation at http://www.sidc.be/products/presto #--------------------------------------------------------------------# # FAST WARNING 'PRESTO' MESSAGE from the SIDC (RWC-Belgium) # #--------------------------------------------------------------------# Incomplete SoHO LASCO C2 coronagraph data show within the covered timeperiod of 23:48UT May 6 and 00:36UT May 7 that a CME associated with the continuous activity in NOAA region 2740 has an asymetric halo character. The CME is primarily directed to the North-East but a faint halo front over the South-West can also be seen during this short period covered by LASCO C2 data. The CME is better covered in time by STEREO A COR2 data where its main core becomes visible starting 16:24UT May 6. A projected speed of around 400 km/s from STEREO A perspective has been estimated. Given the halo character a possible arrival at Earth is estimated in the afternoon of May 10. The main direction of the CME is not directly to Earth though, and given also the speed of the CME, associated increases in Solar wind speed should remain limited. Updates will be provided if additional measurement data require to modify this estimate. #--------------------------------------------------------------------# # Solar Influences Data analysis Center - RWC Belgium # # Royal Observatory of Belgium # # # # Website http://www.sidc.be. # # E-mail sidc-support@oma.be # # To unsubscribe http://www.sidc.be/registration/unsub.php # # # # Legal notices: # # - Intellectual Property Rights: # # http://www.astro.oma.be/common/internet/en/data-policy-en.pdf # # - Liability Disclaimer: # # http://www.astro.oma.be/common/internet/en/disclaimer-en.pdf # # - Use and processing of your personal information: # # http://www.astro.oma.be/common/internet/en/privacy-policy-en.pdf # #--------------------------------------------------------------------#Lead Time: 67.28 hour(s)

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.
