![]() ![]() They are named after physicist Ferdinand Ellerman who studied the tiny blasts in the early 20th century. All this action took place during a brief 30 second exposure.Įllerman bombs are magnetic explosions about one-millionth as powerful as true solar flares. Weiller caught more than a dozen explosions underway in sunpot AR3140 (left) and a few in sunspot AR3141 (right). Sylvain Weiller photographed the phenomenon today from Jerusalem, Israel:Ī sampling of the bombs are circled for reference.

It is flowing from a southern hole in the sun's atmosphere. LONG-RANGE FORECAST: A fast-moving stream of solar wind is expected to hit Earth's magnetic field on Nov.

Credit: SDO/HMIĬosmic Rays Solar Cycle 25 is beginning, and this is reflected in the number of cosmic rays entering Earth's atmosphere. ![]() Sunspot AR3140 has a 'beta-gamma' magnetic field that harbors energy for M-class solar flares. ![]()
