Observational Astronomy

an advanced course (5 credits)

at the Space Physics and Astronomy research unit, University of Oulu

The course period January 5 – March 5, 2021.

Lectures will be given remotely on Tuesday and Thursday at 12-14, whereas

practical sessions will take place on campus on some of Fridays at 12-14
see Peppi for detail.

The course is lectured in English

Teacher: Vitaly Neustroev, MA 302, vitaly[-at-]neustroev.net


Course content:

  • Methods of Observations with modern Space- and Ground- based Telescopes
  • Observational Techniques in Gamma, X-ray, UV, Optical and Infra-Red astronomy
