I have captured this photograph of the sunrise on the Garraf coast for La Vanguardia's Readers' Photos. In the image you can see how the solar pillar has formed over the Mediterranean Sea.
A pillar light is an atmospheric optical phenomenon in which a vertical beam of light appears to extend above and/or below a light source.
The effect is created by the reflection of light from small ice crystals that are suspended in the atmosphere or that comprise high-altitude clouds (for example, cirrostratus or cirrus clouds).
If the light comes from the sun (generally when it is near or even below the horizon), the phenomenon is called a solar pillar, as in this case in Garraf.
This stretch of coast is dominated by the Garraf massif in its central part, which reaches the seashore, and softens towards the ends with sandy and very open beaches.
