A moderately strong solar flare measuring M6.9 was detected around AR 4473 at 19:29 UTC (June 21). It does not appear that a large CME will be associated, however a further update will be provided once new coronagraph imagery is available.
Solar activity increases further with this M2.6 solar flare detected around AR 4473 at 02:46 UTC (June 21). A further update will be provided if any sort of CME is associated with this event. SolarHam.com
What appears to be a shock passage was just detected by the ACE spacecraft at 09:56 UTC (June 13). This is likely the CME observed leaving the Sun on 6/11 arriving a little later than predicted. The solar wind speed increased from around 570 km/s to currently near 650 km/s.
Eruption this morning in vicinity of AR 4461 produced a CME that is now emerging. More to follow regarding a possible Earth directed component. SolarHam.com
Incoming CME detected at 04:31 UTC (June 5). The solar wind speed increased from 400 km/s to currently just above 550 km/s. A passage past Earth is expected within the next hour. SolarHam.com
