CME Note: The source of this signature is somewhat unclear. It could be associated with the arrival of a combination of 2 CMEs that started on 2019-05-10T19:09Z and 2019-05-11T02:39Z. From Dr. Lan Jian: The flux ropes separated by sharp boundaries could be due to the interaction of multiple CMEs. From the in-situ observations and Enlil modeling results, Earth was in the rarefaction before the CME arrived, this may be why the CMEs reached Earth so fast.

:Issued: 2019 May 11 1130 UTC :Product: documentation at http://www.sidc.be/products/presto #--------------------------------------------------------------------# # FAST WARNING 'PRESTO' MESSAGE from the SIDC (RWC-Belgium) # #--------------------------------------------------------------------# In the vicinity of Catania group 16 (NOAA AR 2740), located near disk centre, two material eruptions can be seen in EUV images. The first around 18:25UT and the second around 23:55UT. Coronagraph images from STEREO A also confirm two corresponding CMEs. In currently available coronagraph images from Earth perspective the signatures are less clear. SoHO/LASCO C2 shows, from around 3:02UT, a mainly North-East bound CME of which the angular extent is hard to estimate given the faint signature. It could however be classified as partial halo and correspondingly the presence of an Earth directed component should be considered. With the initiation parameters unclear, the interplay between both CME's is hard to assess. Speed is best estimated from STEREO A data and is for both CMEs low, 300-400 km/s. Based on these initiation parameters, a possible arrival of these CME's is not expected before noon, May 15 and 7:00UT, May 16 respectively. #--------------------------------------------------------------------# # 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: 58.60 hour(s)
