A huge filament on the southeast of the sun erupted towards the end of June 4. The filament was somewhere between a whopping 500,000 – 1 million km in length. This eruption produced a fairly slow coronal mass ejection that […]

A whole lot of spots going on! We no longer have the rumbling region AR11967 but the solar disk is covered with smaller regions and AR11974 is sitting at disk center popping of lots of small and medium-sized flares. It […]

This time a CME is headed directly for us! Around 5:24 UT (1:24 EDT), the SOHO/LASCO C2 instrument caught a first glimpse at a CME leaving the sun directly for Earth. The CME is traveling at a fairly slow ~610 […]
