SOHO LASCO C2 5-15-16 16:00 UTC GOES 14 PTHNA @ 0.4 Seconds 5-15-16 16:45:00 UTC Region 2542 on the western (right) limb appears to have erupted and created a long duration flare andCME outbound westward from the surface at about 15:27:55 UTC this date. The full halo event can bee seen in both the GOES and LASCO images abovre. The magnitude of this event is about C3. Further imaging from LASCO C2 and C3 should determine any Earthbound component of this event in the coming hours. Region 2544 (just north of center disk) also erupted at about 19:25:00 UTC and created a CME which appears to have been re-absorbed in the sun's surface. Further imaging will be needed to analyze this event which is almost on the Sun-Earth centerline.
ACE RTSW SIS 5-15-16 21:21:07 UTC ACE RTSW EPAM Electrons 5-15-16 21:20:07 UTC The Advanced Composition Explorer (ACE) spacecraft instruments are detecting a proton >10 MeV and an electron event reaching the spacecraft L1 Lagrange location (1 million miles from Earth) since the region 2542 event mentioned in the previous post. It takes about 8 minutes (500 to 520 seconds) for light to travel from the sun and reach Earth. Plasma (electrons and protons) ride the solar wind with a boost from the eruption. This event should trigger polar aurora activity and storming (G1 or greater) in the coming hours. More on the ACE spacecraft: http://www.srl.caltech.edu/ACE/
SDO HMI Continuum 6-3-16 01:30:00 UTC Almost Spotless sun. Last zero sunspot day: 7/7/14 (During mid solar maximum). Date: 6-3-16 @ 02:25 UTC SSN: 27 Radio Flux: 85 X-Ray Flux: B1.6 Coronal Hole #83 will rotate into a Geo-effective position in the coming day. Product: Forecast Discussion Issued: 2016 Jun 03 0030 UTC # Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center .Forecast... The geomagnetic field is expected to be quiet to unsettled on day one (03 May). Field activity is likely to reach G1-G2 (Minor-Moderate) geomagnetic storm levels on days two and three (04-05 May) due to the onset of a CIR followed by the influence of a recurrent negative polarity CH HSS.
SDO HMI QLC 6-4-16 00:11:15 UTC Referring to previous post... Product: Forecast Discussion Issued: 2016 Jun 04 0030 UTC # Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center # Solar Activity .24 hr Summary... Solar activity was very low and there were no active regions with sunspots on the visible disk. No Earth-directed coronal mass ejections (CMEs) were observed in available coronagraph imagery. .Forecast... Solar wind parameters are likely to reach G1-G2 (Minor-Moderate) geomagnetic storm levels late on day one (04 Jun) and early on day two (05 Jun) due to the onset of a CIR followed by the influence of a negative polarity CH HSS. Quiet to active conditions are expected on day three (06 Jun) as CH HSS influence begins to wane.
STEREO Ahead EUVI 195 6-4-16 01:55:30 UTC Spotless Sun is confirmed at 0225 UTC 6-4-16. Stereo A imagery is indicating this may continue for the next several days.

SDO HMI QLC 6-17-16 01:45:00 UTC Bottom edge of image is solar equator at the eastern limb. The emerging region on the eastern limb may be the last for the next several days. If this new region continues to grow, it will be in a geo-effective position around 6-26-16. The region maybe numbered 2556 in the coming hours.
If you would like to see the storm develop in real time the MDSR Scanning Seismograph is up and working in Vancouver, BC, Canada. The RF Seismograph image will update every 10min and monitor conditions on 80, 40, 30, 20, 15, 10m.

Product: Forecast Discussion Issued: 2016 Jun 21 0030 UTC # Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center # Solar Activity Numerous CMEs were observed off the North through SW limbs over the past 24 hours. The first CME was observed in LASCO C2 imagery off the NW limb, first visible at 19/1325 UTC, and was associated with a C1 x-ray event observed at 19/1158 UTC from Region 2558. Analysis of this slow-moving CME, and subsequent WSA-Enlil model output, suggested there was no Earth-directed component. Additional CMEs off the W through SW limbs were observed in coronagraph imagery between 20/0200-0800 UTC, all related to eruptive prominence activity. A well defined CME was first observed in LASCO C2 at ~20/1600 UTC with a NNE trajectory from the Sun center. This event was also visible in STEREO A COR2 coronagraph imagery, as well as STEREO A EUVI 195, as a wave depicting a clear source location on the far side of the Sun - taking the transient away from Earth. This thread started June 21 Father's Day 2015. 27 pages and over 27,000 views later this thread comes to an end as it started with multiple CME's at the same time. My purpose was to highlight examples from the point of view of a solar astronomer. Hopefully, this will help you to identify potential events and the complexity of Space Weather Forecasting when viewing solar optical and measurement data. You can bookmark any of the 27 pages for future reference. Many of these examples will be posted on the http://www.sweoc.org/ website under Space Weather Training in the coming weeks. The October 2016 issue of the ARRL QST magazine will feature an article about the 2017 US Solar Eclipse. I am going to provide a project for this event and devote my time to this endeavor. You can follow this project on the GRAPE website: http://www.sweoc.org/GRAPE.html from this date forward. My very best and thanks to all who have viewed and commented on this thread. I have learned from each of you as well. 73's Keith Morin KG7QCK Tucson, Arizona USA
Contact has been re-established with the STEREO-B spacecraft which fell silent October of 2014. A truly remarkable achievement. Congratulations to the team! http://www.cnn.com/2016/08/23/health/nasa-stereo-spacecraft-found/index.html
