ARES has returned to Switzerland🇨🇭 and the aircraft will now undergo routine maintenance before we resume FLT OPs again, likely starting mid next week ✈️. WX FCSTs will again be posted on this channel from end of this week onwards.

ARES Observatory @ares-observatory.bsky.social · 02/08/2026
FIN mission successfully completed with a strong final sortie using a gap ☀️between a high cloud band and convective clouds building! ARES is now en route to Sweden. Strong SW winds create nice sun glint effects in the Finnish Archipelago 😎

ARES Observatory @ares-observatory.bsky.social · 01/08/2026
The mission areas of Pallas and Sodankylä are slowly clearing ☀️ This matches our expectations based on yesterday's FCST. Our schedule remains for now as communicated but may be slightly delayed to match the ongoing clearing of the target areas.

ARES Observatory @ares-observatory.bsky.social · 31/07/2026
ARES has arrived at EFRO (Rovaniemi) ready for tomorrow’s missions. WX FCST for tomorrow SAT remains good ☀️ The sensor is setup to stay cool over night.

FIN WX FCST shows IMG conditions in the South from WED 29 JUL till THU 30 JUL. Olvassuo on THU morning, maybe also on FRI or SAT although uncertain. Northern sites have a window on THU AM, then possibly SUN AM or MON AM. Surisso is completed. We try and finish the South this PM.

ARES Observatory @ares-observatory.bsky.social · 28/07/2026
FIN WX FCST shows IMG conditions in the South and Centre from WED 29 JUL till THU 30 JUL. Northern sites have a window on THU AM. XFER ESKN to EFTP shifted to WED due to heavy WX incl icing en route today. Three possible deployment versions are being planned. More details to come.

ARES Observatory @ares-observatory.bsky.social · 25/07/2026
We have gone through another thorough assessment procedure and decided to move ARES into a Forward Operating Base (FOB) near Stockholm to shorten our reaction time to upcoming WX windows. We will XFER this afternoon, refuelling currently under way.

ARES Observatory @ares-observatory.bsky.social · 25/07/2026
FIN WX FCST is deteriorating again with chances of success dropping rapidly in the last 24 hr FCST period. Absolutely shocking development into another high-risk operation. This is another critical decision point while the aircraft is already north-bound.

We’ve had a fun day of logistics here at LSGC with the team from SFS, moving AVIRIS-4 from the Tecnam to the Caravan. Here is for now the whole aircraft fleet that acts as carrier for ARES 🛩️😎.

ARES Observatory @ares-observatory.bsky.social · 21/07/2026
Successful test flight ✈️ on the Tecnam today over Colombier, all systems worked to satisfaction and we collected more data for geolocation studies by our colleagues at EPFL!

ARES Observatory @ares-observatory.bsky.social · 12/07/2026
Appreciation: A succession of L pressure areas is sweeping across FIN from W to E between 18 and 26 JUL. This trend will continue till end of JUL. GFS suggests a new anticyclonic system to form in the central N Atlantic by 28 JUL. Consequence: We see no opening for a deployment at this point.
000
ARES Observatory @ares-observatory.bsky.social · 11/07/2026
The Omega predicted by yesterday’s models at synoptic time 1200Z has now disappeared. The small chances of clear skies predicted by GFS (see WX clear sky matrix) are unlikely. ECMWF predicts clouds and rain during the week of the 20 JUL We see no opening for a deployment at this point.
