:Issued: 2015 Jun 21 1019 UTC :Product: documentation at http://www.sidc.be/products/presto #--------------------------------------------------------------------# # FAST WARNING 'PRESTO' MESSAGE from the SIDC (RWC-Belgium) # #--------------------------------------------------------------------# A full halo CME is detected with first appearance in SoHO/LASCO C2 images at 2:36UT. It is associated with the double M2 flare from Catania group 92 (NOAA region 2371) located just east off the central meridian (about -13 degrees at the time of the event) peaking at M2.0 level at 01:42UT and M2.6 level at 02:35 UT. A corresponding dimming is visible in SDO/AIA imagery. The halo is fairly symmetric with principle direction only slightly northeast. Measured projected speeds are around 1000-1300 km/s. This CME is definitely earthbound and may interact with the June 19 CME. A combined arrival of those is expected from June 22 afternoon onwards. #--------------------------------------------------------------------# # 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.

The latter peaked at M2.0 level at 1:42UT and at M2.6 level at 2:35UT. It was associated with a dimming and a corresponding full halo was observed in SoHO/LASCO images. Solar flaring at M level is likely over the next days by both regions on disk, which are now on or approaching the western hemisphere. The 10 MeV proton flux was at decline towards background levels but stabilized around 18:00UT at slightly elevated levels of around 0.7 pfu. Since 2:00UT the level is gently rising again to current levels of 2-3 pfu. This is likely to increase further and a warning condition is issued for the coming days. The full halo CME associated to the double peaked M2 flare from Catania group 92 (NOAA region 2371) located just east off the central meridian (about -13 degrees at the time of the event), has its first appearance in SoHO/LASCO C2 images at 2:36UT. The halo is fairly symmetric with principle direction only slightly northeast (CACTUS software erroneously interpreted the event as three separate events with limited angular extent). Measured projected speeds are around 1000-1300 km/s. This CME is definitely earthbound and may interact with the June 19 CME. A combined arrival of those is expected from June 22 afternoon onwards. Solar wind is still at nominal levels with the speed and total magnetic field dropping further to low values of 280 km/s and 2nT respectively. Bz was variable in the +-1.5 nT range. Corresponding quiet to unsettled geomagnetic conditions were recorded (NOAA Kp 0-1, local K Dourbes 0-3). Solar wind conditions are expected to become perturbed later today by a glancing blow from the June 18 CME, followed by the arrival of another glancing blow from the June 19 CME and the arrival of the June 21 CME from the afternoon of June 22 onwards. Minor to moderate geomagnetic storms may occur later today and tomorrow with possibly major to severe storms late June 22 and June 23 associated to the arrival of the June 21 CME.
