On September 4, Mattia Picolli imaged the planet showing a disk and Triton.

On Sep 23, Luigi Morrone recorded a bright spot on Neptune at R/IR wavelengths. This lay close to the planet’s southern limb and was on the CM at approximately 21:20 UT with a longitude of 121 Deg.

On September 24, Martin Lewis imaged the disk and Triton. No detail was recorded on the disk. 

2021 August
The first observations of Neptune for this apparition were made by Darryl Milika and Pat Nicholas (Australia) on August 8. Their images showed a bright white spot south of the planet’s equator. Images taken ~ 83 minutes apart showed the spot moved with the rotation of the planet.

An observation was made by John Sussenbach (The Netherlands) on August 30 showing the disk and Triton.
