Notes on the astrolab to be held from Feb 27 - Mar 10 2023:

  • The astrolab will be held fully in presence at the Landessternwarte on the Königstuhl.
  • In case of any change of the regulations by the University affecting the astrolab we will post it here.
  • The E-mail with the confirmation of participation have been sent out on February 3. The booklet circulated with the confirmation of participation can be found here .

Note: As part of the astro-lab to be held from February 27 - March 10 2023, observations will be carried out with the 70cm telescope of the Landessternwarte Heidelberg. Since weather is normally pretty poor in February/March, the observations will be performed during the lecture period in the Winter-term 2022/2023. Observing sessions are offered Monday/Wednesday/Friday. Since we suffered from bad weather in previous Winter seasons (mostly only a few nights of the 30 nights offered were useful) we will carry out the observations with two groups, with a maximum of 4 students each back to back. The first group at a given day is at the telescope from 16.30h - 19:30h, the second group from 19:30h - 22.30h.

The following dates in Winter 2022/2023 are offered:

HowTo: Pls. register online for the astrolab as detailed below. Then pls. indicate via a GOOGLE spreadsheet all dates, where you would be available for an observing evening. Based on the number of participants and their availability, we will then build groups with a maximum of 4 observers with fixed dates for the observations. Pls. urgently give your cell phone number (if you have one) when registering. At the day of the observations you are scheduled for, you will receive an E-mail from the assistant in charge between 13h and 14h. If something changes on a short notice he will either call you or send you an SMS. If you do not receive anything on that day, no observations will be carried out because of weather.

Registration is now open with the observations starting on October 31. On October 27 the first assignment of observing nights can be found on that page. It will be updated every Thursday.

You can also register at a later stage. Once the first round of scheduled observations is over, new dates for the unsuccessfull students/groups will be defined as well as observing dates for the participants who have registered later on. The assignment of the dates will always been made based on the entries in the GOOGLE spreadsheet.

The assistant for the observations is Bhavesh Rajpoot

Logistics and transportation: Meeting point for the observations is at the gate of the Landessternwarte.

If you come by car, pls. leave it just to the right hand side in front of the gate.

For the ones who require public transport to come up, Bus 39 leaving Hauptbahnhof every full hour (16/19h) is recommended. You can alternatively hop on Bus 39 a few minutes later from the Alois-Link Platz (it is a 10min walk from the Bismarckplatz to the Alois-Link Platz). Arrival at the Landessternwarte is about 25minutes later. You have to walk about 400m from the bus stop to the gate of the Landessternwarte following the sign.

Going down: Bus 39 leaving at 19.32h or Bus 30 leaving at 19.46h from the Landessternwarte (1st group). There is no bus running at times when the 2nd group is done with their observations. Instead the "Ruftaxi" which runs at 22.28h from the bus-stop at Landessternwarte has to be used. It needs to be called 30min in advance at 0621-1077077 for a reservation. The assistant at the 70cm telescope will take care of this. The Ruftaxi is free of charge for the ones with a "Semesterticket", otherwise costs are 1,50 Euro per ride/person.

Preparation and outline of the observations: Pls. download the script for the observations here . For the evening pls. go through the parts 1.1 and 1.2 and prepare for the observations by working on the questions. At the begin of the evening you will first get an introduction to the telescope and the CCD-camera by the assistant followed by a discussion on what you have done for the preparation of the evening. The data taken during the night will be reduced and analysed as part of the astro-lab in February/March 2023.

Pls. have warm clothes with you. It can be very cold at the Königstuhl during the night.

In case not all participants werde able to conduct their observations during the dates offered (e.g. due to bad weather), we may arrange further observing sessions in January 2023.

Observations with the 70cm telescope are voluntarily, they are not a requirement to pass the astrolab.

    Registration required!

    • Ms Wright, LSW Heidelberg, Tel: 06221 - 541781 or online (preferred). If the former, please provide address, phone number and course (PhD, Bachelor or Master). In case of Bachelor or Master, pls. provide also the week preferred and matrikel number. If you are from a different faculty, please provide this information in the "additional remarks" section.

  • Further information:

    • Procedure: There is no special preparation for the astro-lab required. Altogether 11 tasks will be offered. An introduction to the tasks can be found in this document. During the one-week astro-lab about 2-4, during the 2-week astro-lab about 6-8 tasks shall be worked on in groups of two (scripts will be given on site or be made downloadable from the WEB). Individual tasks will be assigned by the organizers. Once a task is completed by an individual group, it will be discussed with one of the responsible assistants. There is no need for a written summary or any homework.

    • Literature: It would be useful to bring your own textbooks, e.g.
      • Schneider: Extragalactic astronomy and cosmology
      • Shu: The Physical Universe, University Science Books

    • Very useful: Bring your own notebook for working on the tasks and/or searches in the internet (WLAN/DHCP available). For the data reduction as part of Tasks 1 and 11 dedicated notebooks will be available. Knowledge of SW-tools like Origin, Excel or Gnuplot to e.g. fit functions to data would be an asset.

    • Due to space constraints the number of participants is limited to 40 students per week.

    The dates for the next astrolab during the Summer term 2022 are from October 2 - 13, 2023. If you prefer to take part during this period, send me an E-Mail. You will be put on a pre-registration list and be informed and allowed to register for that event before it is made public. Your participation will be guaranteed!
