Big Sunspot Faces Earth
Source - Space Weather News for April 1, 2017: http://spaceweather.com
SUNSPOT FACES EARTH: 2017 has been a year of few sunspots. That makes
AR2645 even more remarkable. In recent days, the young sunspot has
grown rapidly into a behemoth more than 150,000 km wide with a magnetic
field that harbors energy for M-class (moderately strong) solar flares.
Because it is directly facing Earth, any eruptions this weekend could
partially ionize the top of our planet's atmosphere and alter the
normal propagation of radio transmissions around the globe.
