Clear skies after yesterday’s storms.  Seeing was bad because of the sidewall of the Jetstream with wind shears between the Sun and my scopes causing high scintillation.  AR2738’s trailing spots have decayed but the leading spot is still well formed and the light bridge can still be seen.  The area covers 250 millionths and one spot.  Full disk images today and close ups of the region in the three wavelengths.
