On April 23, 2012 the Sun showed some interesting features and we were
able to capture all of them in this 5-panel mosaic. While the proms
along the solar limb were not large, there were many. Filaments and
sunspots were also plentiful in this image. Sunspot AR1460 is at the
top of this shot. Coming around to the 2 o'clock position near the limb
is Sunspot AR1462. Continuing down and to the left of AR1462 is
Sunspot AR1459. Moving down and slightly left is Sunspot AR1465 with a
newly emerging Sunspot region directly to its left.
