A Solar Flare


The Sun threw off a mid-strenght M6.5 flare on 2 April. It peaked just after 14:00 UTC. This video from the Solar Dynamics Observatory shows the flare in two wavelengths of extreme ultraviolet light: 30.4 nm and 17.1 nm, color coded yellow and red, respectively.

  1. Pretty.

    After two days of heavy evening and night time clouds here, it’s supposed to be relatively clear tonight, so we can see if Mars is still close enough to opposition to be seen easily. We’re also hoping that it’s not cloudy on the 15th so we can (if we can wake ourselves up at that hour) try to watch at least part of the lunar eclipse.

  2. Mars is visible tonight where we are. It would have been even more interesting if we’d had a telescope, but nonetheless, we all stood on the porch staring into the night sky, and even my teenager enjoyed seeing it. Thank you for telling us about it!
