Partial solar eclipse in Sweden

Posted on Updated on

Unfortunately we didn’t get the chance to see anything behind the thick layer of clouds and heavy mist passing by the entire morning yesterday. However, we had news channels, local radio stations and news papers droping by asking us about facts regarding this fenomena. Seems when it comes to Sweden that only Stockholm had good visibility.

I’m going to attach a few Youtube clips I saved as a memory from this event.



The interviews were made by Swedish national TV (short: SVT, Sveriges Television)

The Sun through H-alpha

Posted on Updated on

Less then 48 hours left before the partial solar eclipse that occurs during the tuesday morning 2011-01-04. I was testing my equipment and saw that there were a few sunspots. The image is photographed with a Canon EOS 50D at ISO 800 through a Lunt LS60THa H-alpha telescope.

The news have already been requesting curiously on details about the partial solar eclipse on tuesday. Regardless the weather conditions we will be there taking care of our guests and giving interviews. If the weather allow us to observe anything I promise to get back here with some photos.

Summer projects and the 472 Roma ockultation

Posted on Updated on

During June-July at Tycho Brahe observatory we were preparing for a large project that would involve the cooperation between many amateur astronomers from different locations in Sweden. The Swedish assosiation for amateur astronomers (SAAF: Svenska Amatörastronomiska Föreningen) helped us to get in touch with other amateur astronomers across the country. Together with my collegue Arne L Ohlsson we started to put hard work on planning, coordinating meetings, assembling nessesary instrumentation and dealing with time pressure.

The ockultation is all about a large rock out in space, or more commonly called an asteroid named 472 Roma passing infront of the delta star (Yed Prior) in the constellation of Ophiucus, causing this large red giant star to dissappear for a around 5 seconds. This asteroidal passage was meant to be easily observed from our location, but negative observations outside the occultation shadow would provide a lot of information regarding the star itself.

It has been mistaken for a long time that the delta star in Ophiucus would be a double and for the first time an asteroid would occult this star and reveal it’s secrets for us. Unfortunately just before the occultation occurred, heavy clouds surounded our area. That was our worse case scenario that just took place, leaving us with unanswered questions.

In the morning we heard that the German and Belgian astronomers were more lucky then us and that many positive reports started to fall in!

Radioastronomy

Posted on Updated on

For almost a week ago we received our radio telescope which was originally owned by the institute of astronomy at Lund’s university. The telescope was used primarily by astronomy students. It weights around 200 kg and is 1,20 m across in diameter. With this telescope we will be able to observe regardless weather conditions and even at daytime the sun, some strong radio sources in Milky way and many other things.

At the same time we have spoken with the architects from the municipality office regarding an extension building northside from our observatory. I will publish soon some blueprints which will give a clear picture of how our future observatory will look like. Because the building plans are not official yet, I’ll have to wait from publishing any further information regarding construction plans until all plans are set.

Last night I held a lecture about Galileo’s telescope for members in our Tycho Brahe astronomy society here in Skåne. I would have kept going with my entire presentation for more then a hour but my time was limited to half. The lecture was describing the difficulties Galileo encountered in order to build his first telescope and the differences and achievements with later versions of his telescopes, as well as his first observations based on Jupiter, Venus and the moon that changed the world’s view.

Unfortunately Bengt Rosengren a member in our astro-society felt ill and couldn’t attend our meeting. He has created a Galileo telescope replica which would be available for our attendees to study. I am providing an image from his replica here.

Astronomy event in Hven

Posted on Updated on

Lecture about variable stars

Came back after an amazing weekend in Hven, a little isle between Denmark and Sweden where astronomer Tycho Brahe once was the head of Europe’s top astronomy researches, trying to resolve problems around the heliocentric model by observing the parallax between stars. We arrived there at Friday morning by car together with Sara and another member of the Tycho Brahe astronomy society.

Sara and I decided to camp by assembling our tent close to the beach on the north-east side of the isle and by the time we were done, we attended our first workshop which was dedicated to Astrophotography. To my disappointment both course leaders were talking 2½ hours about their own telescopes and their old telescopes but nothing about astrophotography… Apart from a slide in their powerpoint presentation with around 30 terms in Astrophotography. During that time Sara had difficulties to keep herself from sleeping, so we decided to abandon this workshop and go for lunch.

The coming days we explored a bit of the isle, eating in most of the restaurants, attending workshops, looking at books, filters, telescopes and talking to professional and amateur astronomers. This event is the first of its kind in Scandinavia partly because we got many participants, but also because it was filled with lectures from professional and experienced amateur astronomers bringing up things about dark matter, exoplanets, variable stars and the cooperation between amateur and professional astronomers in matters of observational data and common research areas.

Within a few days I will post a few links on videos from these lectures and workshops but apart from one lecture in English, the rest was in Danish and Swedish. Unless you understand Danish or Swedish I really recommend you to watch the lecture in variable stars given by Christopher Allen.

One thing that really brought up my curiosity was a lecture in Spectroscopy by Køge Bugt. It is amazing what amateur astronomers got in their hands when it comes to advanced equipment but also their enthusiasm on this kind of homemade research!

The event days came to an end by a few lectures from professional astronomers and a few words from the head of the board from Tycho Brahe Astronomy Society. This event went beyond my expectations thank to all effort, enthusiasm and energy that came from all the participants and people behind the scenes. I will get back with more photos soon!
