Just after sunset, the sea (below left), some terrain, hills and rocks on the right and the sky above. Looking westwards from Sounion
Microburst with hail over the northern suburbs of Athens. A hill with buildings in the foreground and clouds in the background
The southern part of Athens, Greece, with 2 lightning bolts and cloudy sky at noon
A CG lightning triggers an "inverted" one, GC, in the background, possibly from wind turbines. The photo shows lightning with the northern parts of Athens in the foreground, hills and mountains in the middle and stormy clouds on top. On the bottom left, there is a small image zooming in on the ribbon-y nature of the CG strike.

Wide angle photo of the sky with a contrail, the sun, thin cirrus clouds, some dusty atmosphere and 2 halos forming concentric circles around the Sun
22 deg. solar halo, among clouds in the sky and a contrail through it.

A colored band among clouds in the sky. Circumzenithal arc
Comet PanSTARRS in black and white with the starry sky as background
The southern parts of Athens with Acropolis and Parthenon almost at the center. The sky above the city is full of clouds as a thunderstorm is ongoing but the dark red-brown hue is due to an African dust transfer.

Thunderstorm at night, over the sea
A map with spots of successful observations of the aurora on Jan. 19, 2026 from Greek-based observers. Also, there is a grey area on the map, pointing out where cloud coverage was significant thus making aurora observation not possible.
red sprites at night, on a starry sky with clouds and the flash of the parent lightning below. At the bottom one can observe the mountains of Evia isl. The observer is on E. Attica, Greece, looking eastwards.
An upward unconnected leader (or upward streamer) is a positively charged channel of ionized air that rises from ground objects (like buildings, towers, trees or even the ground itself) towards a negatively charged downward-moving "stepped leader" from a storm cloud. When an upward leader "connects" with a downward leader, the lightning bolt we see occurs. It is possible to catch (in a photo) one or some of the upward leaders who "didn't make it" to connect with the downward one.

Red sprites over severe thunderstorms at NW Greece, as seen from Athens. Red filter used in order to cut light pollution below 630 nm, that's why the photo appears a bit more reddish than normal.

A majority of the European Union's foreign ministers backed a Dutch proposal to review the bloc's ties with Israel over its actions in Gaza. Flags of the countries voted in favour of this proposal, against it, and being neutral. A disgrace for GR and CY to align with WWII Axis. What a F disgrace when people are executed in front of our eyes!
