=== LOT Call-of-Proposal: 2025C Semester === This is call-of-proposal for Lulin One-meter Telescope (LOT) for Semester 2025C (from 01 September to 31 December, 2025). The proposal is divided into two categories: Education -- use the latex template given in LOT_Proposal_Education.zip for this category. Research -- use the latex template given in LOT_Proposal_Research.zip for this category. Deadline: *** 31 July 2025 (before midnight local Taiwan time) *** Kindly send your proposal as single PDF file, including the compiled proposal PDF and a separate one-page file for any figures and/or tables. Please do not send LaTeX source files. Please send your submission by email with the subject line "LOT 2025C proposal" to the following address: twchen@astro.ncu.edu.tw IMPORTANT MESSAGE: (A) Rapid ToO Triggers: Since semester 2025A, ToO Triggers have been catalogued into Rapid ToO and Normal ToO. The Rapid ToO Triggers at LOT has been established with the highest priority for immediate follow-up on transient phenomena such as gamma-ray bursts, fast X-ray transients, fast radio bursts, and supernovae. This mode is designed to interrupt ongoing observations, including non-disruptive programs, to ensure swift and timely data capture for these urgent events. For Rapid ToO requests, please provide a strong science justification within your ToO proposal. (B) Following nights are not available. If your targets can be observed near full moon, we may still allocate these dates depending on the schedule. 8 Sep -- Engineering/Full Moon 7 Oct -- Engineering/Full Moon 5 Nov -- Engineering/Full Moon 22 Nov -- ISYA 2025 29 Nov -- ISYA 2025 5 Dec -- Engineering/Full Moon * For educational programmes, during the university sports event from November 4 to 6, most Lulin staff will return to campus, with only one observer on duty at the observatory. Hence no educational observations during this period. (C) UVEX spectrograph is open for general use since 2024C semester. Please see the instrumental page on Lulin website for more details. (D) LATTE is open for general use by NCU users since 2024C semester. LATTE is a 50cm telescope in TAOS-A enclosure and can be operated fully remotely. Its FoV is 44’ by 33’ and rotatable. The pixel scale is 0.45 arcsec. Filter array contains Johnson-Cousins B,V,R,I broadband filters, Ha and [OIII] 5nm narrow-band filters, and a visible light white-light super-broadband filter. The BVRI filters are of square-shaped passbands (see filter curves in http://tinyurl.com/bdebjzf3). 1-hr 5-sigma limiting magnitudes are between 22.5 and 23.2 (Vega) in B,V,R, under typical conditions. In the first few trimesters, we will offer time in the share-risk mode, for the users and LATTE to get familiar with each other. In this call for proposal, we offer a total of up to 20 nights to NCU users under dark and gray conditions. More nights can be offered around full moon, if there are observations that can tolerate the moonlight. If you wish to use LATTE for your program, please select it as your instrument in the Latex template. Please contact whwang@asiaa.sinica.edu.tw if more information about LATTE is needed. * For educational programmes, LATTE offers up to three runs/groups this semester. It is required that the PI (or a designated TA) is already familiar with how to operate LATTE prior to the observations. (E) The LOT CCD imager is Sophia 2048B. (F) Starting from the 2021A Semester, on nights when the Lulin CCD imager is equipped, some time may be allocated to a special/filler program. If you prefer not to share nights, please mark "NO" in Section 13 (default is "YES"). However, please note that Rapid ToO triggers may still occur even on non-shared nights. (G) Proposals using LISA or UVEX spectrograph are required to have observer(s) going to Lulin Observatory. Please also note that it is currently not possible to exchange the instruments at the same night due to the instrumental limitation. (H) We strongly encourage observers (especially students) to be presented at the Lulin Observatory, instead of queue observing. (I) For proposal(s) re-submitted from past semesters, please address TAC comments. Proposal(s) that do not show improvement will be rejected. (J) The typical proprietary period of data is 5 years. (K) The proposed number of on-site observers should not exceed 17, except for educational programs, which allow up to 25. (L) Please indicate in the proposal if the PI of the program may bring extra people to observe on site (even if it is not confirmed yet). This is to inform the observing staffs prior to your observation to facilitate the arrangement of accommodation. Note that late submission will NOT be accepted. For information regarding LOT and/or available instruments, please check Lulin's website (www.lulin.ncu.edu.tw) or consult with Lulin observing staff (lulinobsstaff@gm.astro.ncu.edu.tw). ToO policy: * Maximum of 2 hours of ToO interruption per night, including both Normal and Rapid ToO. Normal ToO: * Please inform and negotiate with the original PI in advance. The original PI/observer has the right to accept or decline the Normal ToO request. * Send the Normal ToO request to the Lulin observing staff at lulinobsstaff@gm.astro.ncu.edu.tw Rapid ToO: * Has the highest priority on LOT and will interrupt ongoing observations, including non-disruptive programs. The original PI/observer will be notified if a Rapid ToO is triggered. * Send the Rapid ToO request via the Lulin Slack channel. The accepted proposals and schedule for 2025C Semester will be announced at Lulin's website (www.lulin.ncu.edu.tw) in mid-August 2025.
