The��ESO Headquarters in Garching (Bavaria, Germany)��are located very near the line of maximum totality, about halfway between the cities of Munich and Freising.

The present website is specifically concerned with the viewing opportunities and related events in this geographical area.

The ESO Headquarters are not open for the public on this day. The next��Open House Day��is on Sunday, October 10, 1999.

Latest News

August 18, 1999

A��comprehensive report��about this event,
as seen from the ESO HQ in Garching, and with many photos of the eclipse,
is now available on the ESO web.

August 12, 1999 - the day thereafter

About 500 people watched the eclipse from ESO HQ. The view of the event was as described in the dispatches below. From the reports from sites along the totality band across Europe, it appears that we were reasonably lucky. The weather was not so good further to the west - it was better in the south-east corner of Bavaria and we were near the border in between.

Some ESO people and their friends took photos. We will put some of them on display at this website in due time.

It was a very special experience for all of us. And it was certainly a unique day in ESO history!

Carolyn Collins Petersen��from "Sky & Telescope" participated in the conference at ESO and watched the eclipse from the "B��rgerplatz" in Garching, about 1.5 km south of the ESO HQ. She managed to see part of the totality phase. You will find her dramatic report(s) at the��S&T Eclipse Expedition website.

There has been severe web congestion during the past days, due to the eclipse. This webpage had about 20,000 hits yesterday and there were also very many on the "Astronomy On-line" Eclipse site.

August 11, 1999, 13:00 CEST (11:00 UT)

It is over! We were partially lucky in the sense that we saw the almost eclipsed Sun up to about 10 minutes before totality and then again just when the second "diamond ring" appeared at the end of totality. Then the skies were almost clear and we could follow the partial phase. We are told that just 5 km from here, people were more lucky and saw the entire total phase. But the whole atmosphere was fantastic - we had all the local effects, the darkness, the cold wind and the silence. We were all very impressed!

August 11, 1999, 12:00 CEST (10:00 UT)

The eclipse is well underway in Garching. The sky is heavily clouded, but we have seen the eclipsed Sun through several holes, as the Moon gradually moves in front. Just now, another heavy cloud is moving in front, but there is hope in the form of another clear hole behind!

August 11, 1999, 07:45 CEST (05:45 UT)

The chances in the M��nchen area have improved somewhat. See the above METEOSAT images, obtained in a water vapour band at 02:30 UT (04:30 local time) this morning (left) and an infrared band at 05:00 UT (07:00 local time) this morning (right). The main concern is an approaching front - will it reach M��nchen before the eclipse? The better chances are now further east, nearer the Austrian border.

August 10, 1999, 18:00 CEST (16:00 UT)

Note the most recent��special forecast for the M��nchen region (August 11)��that appears slightly more optimistic ("Schauerwolken am Vormittag, mittags vereinzelt Aufheiterungen, nachmittags eine Mischung aus Sonne und Wolken bei 20 Grad").

August 10, 1999, 11:00 CEST (09:00 UT)

The weather forecast is unfortunately��rather desolate for the Munich region��- indeed for most of Southern Germany and Austria. There is almost complete agreement among the various sources of meteorological forecasts that a front with bad weather will be passing across Central Europe tomorrow, the day of the eclipse.

The estimated percentage chance that the Sun may be visible during the eclipse is only about 20% in M��nchen and even less east of this city, immediately north of the Alps (e.g. in Salzburg). The prospect of clear skies increases somewhat towards the west and may reach about about 50% in western France. Towards the east, there should be up to 70% chance east of Budapest.

You may follow the development of the weather front in a��METEOSAT-IR mpeg movie��that is regularly updated.

Eclipse Path and Circumstances

��

Map from F. Espenak's eclipse website.

The total phase of the eclipse in Garching will begin at about 12:37 local time (10:37 UT) and the total phase will last about 2 min 15 sec. The altitude of the Sun above the horizon will be about 56^o. According to available weather statistics, it is estimated that there is about 50% chance of seeing the eclipsed Sun in the sky without interfering clouds.

A TV test image

A test sequence of solar images was made with a professional TV camera and a special filter from outside the ESO building on July 29, 1999. Here is one of the frames, as an example. Several sunspots are seen.
