Watercolor Prom

Solar Prominence - April 22, 2012
Solar Prominence – April 22, 2012

Object Name (Sun)
Location (Rocbaron – Var in Provence)
Date (April 22 2012 16h12 local time)
Media (white paper, emerald green watercolour, inverted scanning.)

Hello artists

Just a few hours after the great sketch of Stratos Tsanaktsidis, I had the opportunity to draw this one. I use a common H alpha PST Coronado.

My technique is quite original, after a light circle portion made by a graphite pencil on white paper I use directly a pure watercolour “green emerald” to sketch the solar surface on a water base and then the protuberances on the dry part of the sky, taking into account that light green will become dark red and vice-versa. Then I just have to invert the colours after scanning. The white sky is becoming black while the green part is becoming “H alpha red”.

Right, I add the approximate dimension of the earth and the moon orbit.

Clear sky to you all

– Equipment: Coronado, special instrument to observe the Sun

– Location: Castres (France)

The sun’s activity is very important in this moment, causing greats eruptions that I drew the best I could. Note that few sunspots appear (maximum 2). The dark lines on the sun are eruptions pointing in our direction.

Sincerely,

Late August Sun – 2013

H-Alpha Sun – August 22-31, 2013

Location : Castres, south-west France (near Toulouse)
Date : from 22 to 31 august 2013
Media : graphite pencil, white paper

Comments :
Dayly sketch of sun made through a small Coronado PST (H Alpha) + 15mm Televue eyepiece
Method :
1) dayly observing sun coronado around 12h TU
2) quick sketch with ballpen on paper notepad (2 minutes)
3) later copy out on drawing paper with graphite pencil (10 to 12 minutes)
4) picture take of each drawing with camera + Photoshop processing
– flipping horizontally and vertically in order to see the correct sun orientation
– grouping the 9 pictures + date on the same sheet
One may see the sun rotation from August 26 to 29 watching at spots.
I saw some material projections ejected into space (see August 30)
We currently have a great solar activity
To see the solar prominences evolution one should have to observe every hour !

Thank you for taking into consideration this small contribution
Best regards.
