SOHO LASCO C2 4-12-16 05:00:00 UTC Mission Manager Update: Kepler Recovered from Emergency and Stable Mission operations engineers have successfully recovered the Kepler spacecraft from Emergency Mode (EM). On Sunday morning, the spacecraft reached a stable state with the communication antenna pointed toward Earth, enabling telemetry and historical event data to be downloaded to the ground. The spacecraft is operating in its lowest fuel-burn mode. The mission has cancelled the spacecraft emergency, returning the Deep Space Network ground communications to normal scheduling. http://www.nasa.gov/feature/mission-manager-update-kepler-recovered-from-emergency-and-stable Product: Forecast Discussion Issued: 2016 Apr 12 1230 UTC # Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center # Solar Activity .24 hr Summary... Solar activity was low. Region 2529 (N09E22, Eki/beta) produced multiple low level C-class flares throughout the period. Despite this increase in activity, Region 2529 showed indications of slight decay in its intermediate spots and slowed growth in its larger leader spot. Region 2530 (N15W17, Cso/beta) was absent of significant flare activity while displaying signs of slight decay. <visible in LASCO image above> Other activity included two CMEs off of the south and east limbs that combined to produce a partial halo CME signature. Activity is first visible in LASCO/C2 imagery at 12/0224 UTC. A Type II (215 km/s) radio sweep occurred beginning at 12/0153 UTC and is believed to be associated with this event. Forecaster analysis determined that it is far-sided activity as there is a large filament eruption visible in STEREO EUVI imagery near the same times.
Image: SDO AIA 304 4-18-16 00:43:19 UTC Region 2529 is currently located on the right (west) just north of the equator which appears to be the source of several events in the past few hours. Note Alert Event times in the messages below. The flare reached a preliminary magnitude of M6.7 at 00:20:00 UT. It appears a CME is in progress but due to the location may not be Earth directed.

This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications. #------------------------------------------------- Space Weather Message Code: SUMXM5 Serial Number: 143 Issue Time: 2016 Apr 18 0044 UTC SUMMARY: X-ray Event exceeded M5 Begin Time: 2016 Apr 18 0014 UTC Maximum Time: 2016 Apr 18 0029 UTC End Time: 2016 Apr 18 0039 UTC X-ray Class: M6.7 Location: N10W62 NOAA Scale: R2 - Moderate www.swpc.noaa.gov/noaa-scales-explanation Potential Impacts: Area of impact centered primarily on sub-solar point on the sunlit side of Earth.

Image: SWPC Synoptic Map 5-6-16 1545 UTC Image: SDO AIA 211 5-6-16 22:24:36 UTC Circle and Inset: Coronal Hole (CH #78) Square: Region 2541 It appears negative polarity CH #78 may effect Earth from 5-6-16 2300 to 5-8-16 1200 UTC. The peak effect around 5-7-14 1900 UTC. Solar winds should peak around 5-9-16 0000 UTC. Region 2541 has about a 10% probability of C level flare activity over the next 12 hours.
Image: SDO HMII QLC 5-15-16 12:41:15 UTC While transiting across the far side of the sun, old region 2537 appears to have grown in size since 4/27/16. It has rotated into better view and is now numbered new region 2546 and is classified as an Alpha (low magnetic strength). It is located about 7 degrees south of the solar equator which could pose a threat to Earth in about 6 days (May 31). This region is about 250 times the size of Earth. Old region 2533 should rotate into view just north of 2546 in a day or so along the eastern limb. Product: Forecast Discussion Issued: 2016 May 15 1230 UTC # Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center # Solar Activity .24 hr Summary... Solar activity reached low levels this period due to C-class flare activity. Region 2543 (S05W70, Cro/beta) produced two C4 flares at 14/1519 UTC and 15/0409 UTC which were the largest events observed this period. Region 2544 (N20W08, Dao/beta-gamma) underwent growth this period and increased in magnetic complexity while the remaining active regions were stable or in decay. No Earth-directed coronal mass ejections (CMEs) were observed in available coronagraph imagery.
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.
