This amazing picture was taken last night at the Bharati Indian Base Station in the Larsemann Hills of Antarctica. The researchers there report that the aurora was so bright that it cast shadows.
Yesterday I was having a nice 40 meter SSB contact with N3TDE. Rich is 179 miles away, in Pennsylvania. At 1650 UTC, his signal very suddenly dropped into the noise.
The purple lines along the bottom of the chart below probably explains both the aurora and the abrupt end of my 40 meter contact.
