Dear All,

Just a quick note to clarify my previous posting, part of which read, “More commonly known as “Sprites” these particular events were in actual fact “Blue Jets” and occurred close to the Isle of Man.”

Having exchanged emails with Dr Martin Fullekrug (University of Bath), the observed TLSs are actually known as “Column Sprites” and not “Blue Jets”. Blue Jets are a different phenomena and emanate directly from the cloud top (ie at a much lower altitude). Apologies for any confusion caused.

In addition, the two small bright luminous regions below the leftmost column sprite are known as “beads” and are considered to be an interrupted column.

Best regards
