Comet 46P/ Wirtanen – “Ghostly Green Comet”

I am sharing my take on the passage of this little comet 49P/Wirtanen, also known as the “Ghostly Green Comet”. On December 16, 2018, Wirtanen passed 11,620,000 km from Earth (it will be the closest to Earth in 70 years).

Also visible in the photo are the Pleiades (the seven sisters), or M45, in the constellation Taurus.

Summary Authors: Paulo P. Pereira; Jim Foster

One afternoon earlier in the spring I noticed this striking Sun pillar on the western horizon. It was visible for more than 30 minutes. After the Sun had set it turned red and pink (lower right photo). If ice crystals are stacked horizontally in cirrus clouds and tipped in the direction of the viewer, then the Sun’s waning light is reflected in the form of a column or spike. Note also the extended sundogs on either side of the pillar, approximately 22 degrees from it and the position of the Sun. Photo taken on April 16, 2018.

I’m very glad this picture was nominated as Earth Science Picture of the Day. A big thank you to USRA and the EPOD team, so as to Dr Jim Foster for the brilliant summary.

When The Stars Align – Solar Eclipse

When The Stars Align – Solar Eclipse

Capturing a partial solar eclipse in Portugal, in a cloudy day, is a strike of luck. However, I had the feeling that I needed to go somewhere and try photographing it. Most of the times, photography is about subconscious messages and intuition. Thus, I went to Santa Rita Beach and I had the biggest surprise of the year. There it was – the incomplete sun lurking.

My amazement grew more when I realized that even the eclipse was aligned with the walkway. There’s a mathematical coincidence that I could hardly imagine to be possible. It was a true blessing having the opportunity to enjoy that moment and capturing it.


Registar um eclipse parcial do sol em Portugal, num dia nublado, é um golpe de sorte. Contudo, tive o pressentimento que tinha de ir algures e tentar fotografá-lo. Na maioria das vezes fotografar baseia-se em interpretar mensagens do subconsciente e a intuição. Assim, fui à Praia de Santa Rita e tive a maior surpresa do ano. Ali estava ele – o sol incompleto a espreitar.

O meu espanto elevou-se quando me apercebi que o próprio eclipse estava alinhado com o passadiço. Há uma coincidência matemática que dificilmente poderia imaginar ser possível. É uma verdadeira gratidão ter a oportunidade de aproveitar o momento e registá-lo.
