Съдържание

PLANETARIUM ROUND – ANSWER SHEET 3 projected images with questions. Each part is 15 minutes long. Total time: 45 minutes.

Внимание: Бележка към темата

This is an answer sheet for a planetarium round: the questions refer to a sky projected in the planetarium, which is not contained in the archived PDF. Many sub-tasks (marking positions on a star chart, determining azimuths, seasons, coordinates) cannot be answered from the printed pages alone.

Условие

This is the sky above Keszthely at midnight. The projected sky does not show any Solar System objects.

QUESTIONS / TASKS:

1.1. There are 3 novae on the projected sky at 2nd magnitude. Mark their positions by circles on the star chart. (Please circle only 3 stars. If there are more than 3 circles, then each one in a wrong location will result in 1 point deduction.)

1.2. The Messier objects have been removed from the star chart given you. Mark all the Messier list globular clusters present in the projected sky on the star chart using crosses (X) and write the Messier number of each object near the cross marks.

1.3. The projected sky corresponds to the second half of which month (at midnight CEST) in Keszthely? Circle the correct month.

JAN / FEB / MAR / APR / MAY / JUN / JUL / AUG / SEP / OCT / NOV / DEC

1.4. What is the local sidereal time? (To an accuracy of 15 minutes.)

……………………………

1.5. List six zodiacal constellations, which are partly or entirely visible. (Use the official IAU abbreviations or IAU designation. Every constellation named which is not visible in the projected sky will result in 1 point deduction.)
