Sighting Details

There were 2 basking sharks ( my believe with naked eyes) the one nearest caught my attention from farther away with 3 times tail slapping (1 slap) prior to slowly going under water for approximately 3 minutes then appear again, slowly swimming in a controlled area swim prior to immersing under water again, repeating the same action for the 30 minute observation. The 2nd one was showing less movement as far as repeating the same pattern but in a slower format. Swim, sink quietly, similar timing and swam slowly on top of.the water prior to going under again. I had not got my binoculars or camera with me just phone camera. No gannets either which you would expect but with the current covid situation birds in general seem less in areas.

Plankton sparkling on the sea... calm warm early morning but unsure of sea temp.
