After the partal phases of a solar eclipse,,,or before or any day when there are no eclipse, the pinhole camera effect shows the sun in its full glory...no crescents visible anymore!,,,,, After the eclipse the temp went so high near Sparta, Tn, that the thermometer went for its second turn!!!....believe me...it was not minus 50 degrees!!!!! It really was 60 Celcius...140 F !!!!
