1. KVN Call for Proposal (Single Dish)

===========================================

Call for Proposals 2024B (Single Dish)

Proposal submission deadline: 2024 June 3, 08:00 UT         

KVN website: http://kvn.kasi.re.kr

===========================================

The Korean VLBI Network (KVN) invites scientific proposals for single dish observations for the 2024B season from Korean astronomical community. Observations of successful proposals will be scheduled between 2024 September 1 and 2025 January 15. Proposals should be submitted via the KVN website (http://kvn.kasi.re.kr) before the deadline of UT 08:00 (KST 17:00) on 2024 June 3.

The Korean VLBI Network (KVN) is operated by Korea Astronomy and Space Science Institute (KASI, http://www.kasi.re.kr). Its three 21m radio telescopes are located in Seoul, Ulsan and Jeju Island. Both spectral and continuum observation modes are supported. Available frequency bands are K (18-26 GHz) and Q (35-50 GHz), 86 (85-116 GHz), and 129 (125-142 GHz) GHz and simultaneous observation of the four frequency bands is also possible. For each KVN telescope, 500 hours of single dish observation time is available for this call. Therefore, total available time for three KVN radio telescopes is about 1,500 hours.

Proposers should use the KVN single dish application form and carefully follow the instructions on the KVN website. The scientific and technical justification must be provided within 3 pages. Details of the information and current status of the KVN can be found in the KVN status report on the KVN website (http://kvn.kasi.re.kr).

2. KVN Call for Proposal (VLBI)

===========================================

Call for Proposals 2024B (KVN VLBI)

Proposal submission deadline: 2024 June 3, 08:00 UT

KVN website: http://kvn.kasi.re.kr 

===========================================

The Korean VLBI Network (KVN) will conduct VLBI observations during the 2024B season, which spans from September 1, 2024, to January 15, 2025. Due to the H-maser malfunction at KVN Tamna, astrometric observations will not be available. However, KVN will still support VLBI observations for fringe search or test observations with a single baseline. Proposals should be submitted via the KVN website (http://kvn.kasi.re.kr) before the deadline of UT 08:00 (KST 17:00) on 2024 June 3.

The KVN Pyeongchang 21 m telescope will participate in the 2024B semester on a shared-risk basis, with availability limited to a select number of receivers. 

Specifically, the CTR (K/Q/W-band) receiver will be operational, though the offered observing time may be adjusted based on installation and maintenance requirements as the development progresses.
