Hey Fellow Astrocasters!
The Sun is FINALLY showing signs of activity that MAY signal the end of this historic solar minimum….historic in the length of time that solar sunspots and related activity have been absent.
STEREO A & B twin spacecraft caught the view of an active region that has delighted solar observers since rotating into our face on view of the Sun.
In our current episode I talk about Solar Tsunamis on the Sun. With perhaps the beginnings of Solar Maximum and associated solar activity not far away, we may get more Solar Tsunamis on the Sun.

In a paper to be published in the Astrophysical Journal Letters, available online now here, a team of British astronomers address the concerns some have stated over the recent quiet Sun. Apparently, using the techniques of helioseismology, which like its namesake seismology, uses surface waves to determine what is happening beneath the surface, astronomers have discovered that there is evidence of quite a bit of activity just beneath the surface of the Sun or photosphere. Apparently there is “activity-related
processes occurring in the solar interior, which are yet to reach the surface.”
