Total Solar Eclipse as observed at Ebro Observatory

On 11-12 August 2026, the IAU Working Group on Coordination of Synoptic Observations of the Sun and the International Space Weather Action Team on Data sets of historical observations of solar and geomagnetic activity (S1-03) held a joint workshop on "Synoptic ground-based solar observations for space weather and space climate". The workshop took place at the Ebro Observatory and included presentations about preservation of historical data, use of historical data for modern scientific research, current state of observational facilities in different countries, and plans for future networks of synoptic observations (ngGONG and SOLARNET/SPRING). The workshop was attended by scientists from Belgium, Czech Republic, Germany, Japan, Spain, Switzerland, and USA. On the last day, the workshop was visited by Dr.  Núria Montserrat, Minister for Research and Universities of the Catalan Government and Ellen S. Baker, a former NASA astronaut. Photo 1 shows (left to righth) Dr. Juan José Curto, Dr.  Montserrat, and Ms. Baker greeting the workshop participants. Their visit was related to the activities organized by the Observatory with respect to public viewing of the total solar eclipse.

 

The event included several public lectures about the history of Ebro Observatory, space flights from the perspective of former Spanish and US astronauts, astronomy studies of exoplanets, and space weather effects on Earth (photo 2). Before and during the eclipse, the observatory personnel was taking measurements of the atmospheric properties (wind, temperature) using small weather balloons (photo 3). Children were invited to draw pictures of solar atmosphere and stellar nebula (photo 4). 

 

Total solar eclipse took place at the end of the day during the sunset (see photos 5 and 6). After the dark, the evening concluded by public viewing of Perseids meteor shower.

Getting ready for the eclipse?

The last total solar eclipse in Spain happened on August 30, 1905 (121 years ago!) and so, perhaps it is not surprising that the signs of this year eclipse (August 12, 2026) are everywhere. Would you like to try "Eclipse 2026" ice cream (photos 1-2)? Or perhaps, come to a roof-top at a hotel in Barcelona (photo 3). Eclipse creme brulee anyone (photo 4)? Photos 5-6 show eclipse signs for the public viewing event at the Ebro Observatory (Observatori de l’Ebre) in Tortosa, Catalonia.

 

GONG CT status update from 10 Aug. 2026

Local team at CTIO informed us that the UPS and workstation were on at GONG. NSO engineering team was able to access GONG station remotely. Data acquisition was started and verified. The PMFLAG has been turned off and all looks good.  The turret is still covered and the roll/pitch amplifiers remain off. The weather forecast for the next days is not good. Depending on the weather, the CTIO  team will return to the summit on Friday (8/14) or Monday (8/17). At that time, we could attempt restarting GONG observations.

Solar total eclipse is in one week

 We are 1 week from totality!

The Predictive Science Inc. was running their data-assimilative model in near real time and updating the prediction for over 15 days now.  Attached image shows the current prediction for a locations near Palencia, Spain. For more up-to-date predictions, see https://eclipse.predsci.com

 

GONG CTIO Status, 5 Aug. 2026

On 5 Aug., CTIO team stopped by GONG station and manually powered up GONG UPS. The UPS was restarted and most of the equipment started up. GONG no longer appears to be in a shutdown mode. This should enable the NSO team to remotely login to GONG. Attached are two photos of GONG from outside. There are no visible damages to the shelter or the instrument. For now, we will keep turret covered by the bag in case of bad weather.

 

Chile Storm Recovery Update: 3 August

Recovery efforts continue at NOIRLab's Chilean facilities following July’s historic winter storm. After fresh rain and snow paused recovery work late last week, crews returned to the mountains over the weekend. Today, teams are evaluating whether it is possible to reach the summit of Cerro Pachón.

Heavy equipment crews are actively clearing snow and repairing access roads. The primary bottleneck remains extensive road damage between the Control Puerta and the El Quisco junction, including a large drop-off at kilometer 14 requiring a temporary bypass. It currently takes a three-hour drive to reach the summits.

 

While commercial power has been restored to Cerro Tololo, the service is unreliable, and today the team switched back to generators. Cerro Pachón also relies on generators due to severe power infrastructure damage. To conserve fuel, generators will be turned off at the end of each day, until full-sized delivery trucks can reach the summit. Teams are currently bringing up small diesel loads in pickup trucks. The status of the Cerro Tololo water pump house and distribution system is still under investigation.

Sculpture of the Laocoön and solar eclipses

 The Uffizi Gallery (Florence, Italy),  one of the largest and best-known museums in the world, holds a collection of priceless works from the period of the Italian Renaissance. One of these is the Laocoön sculpture by Baccio Bandinelli (Florence 1493-1560). 

The sculpture depicts the Trojan priest and his sons crushed by sea serpent sent by Poseidon to stop him from revealing the deception of the Trojan horse devised by Odysseus to help the Greek army enter the city of Troy. One can find more about the history of this sculpture at the Uffizi web site. 

The stature rests on its original pedestal. Two sides of this pedestal show identical reliefs, which caught the eye of this astronomer. What the reliefs show is the geometry of total solar eclipse. Two half-spheres represent Sun (surrounded by spiky corona) and the Moon. Two lines connecting the edges of the Sun and Moon mark the outer boundary of umbra, the darkest part of shadow cast by Moon blocking the sunlight. Two other lines show angles at which the lunar disk would be seen from each side of umbra.

By the way, next solar total eclipse will take place on 12 August 2026. It starts in Greenland, passes over North Atlantic Ocean, parts of Iceland, Spain, and it ends in the Mediterranean Sea. In Florence, it will be a partial solar eclipse with maximum obscuration of 92.07%. Several teams of scientist from the US National Solar Observatory will travel to Spain to observe this total eclipse. We will post updates from these eclipse expeditions later.
