AOT 40 TNG REM Call for Proposal. Deadline Monday May 20th, 2019

also featuring NOT time

AOT 40 (2019B) is now open for proposals.
Applications for observing time for the periods

November 1st, 2019 - March 31st, 2020 (TNG)

October 1st, 2019 - March 31st, 2020 (REM and NOT)

are solicited and should be submitted by
Monday, 20th May, 2019, 12:00 UT.

After 8 years, the aluminizing of the TNG mirrors is scheduled during the whole month of October 2019. Therefore, only five months are available in AOT40. The number of nights allocated to ongoing programs and international calls have been reduced consequently.

The available time offered at TNG via INAF-TAC is 10 (ten) nights in this call. This offer can be increased if not all the nights assigned to other calls will be effectively allocated by the respective TACs. The foreseen schedule breakdown is reported at the bottom.

We will be accepting (few) Directory Discretionary Time proposals during the whole semester (, which will be judged by the TNG staff in few days. These observations will be performed in Service Mode only.

TNG is a 3.58-m optical/infrared telescope located at Roque de Los Muchachos Observatory in the island of La Palma (Canary Islands). Its primary mirror is corrected by Active Optics and it is equipped with instruments for imaging and spectroscopy, spanning the optical and near infrared wavelengths range.
The offered instruments are: HARPS-N, NICS, DOLORES and GIANO-B (GIANO in Nasmyth B).
The observing mode GIARPS, simultaneously combining HARPS-N and GIANO-B, is also offered (see below).

REM is a 60-cm robotic telescope located at La Silla ESO site (Chile) which can observe simultaneously with a visible and an infrared camera. The observations will be carried out in unmanned, queuing mode. INAF-TAC will allocate 1000 hours of observations.
REM is equipped with ROS2 visible camera and REMIR infrared camera. The two are observing simultaneously thanks to a dichroic.
ROS2 will produce simultaneous images in the four Sloan-like passbands g, r, i, z. Charged time is therefore not the sum of ROS2 and REMIR, but the greater between the two.

NOT is a 2.56-m telescope, also located at Roque de Los Muchachos Observatory, next to the TNG. Offered instruments are ALFOSC (UV-optical imaging, polarimetry and low-resolution spectroscopy), NOTCam (NIR imaging, polarimetry and low-resolution spectroscopy), FIES (High-resolution, high-stability optical spectroscopy), MOSCA (High-resolution, high-efficiency UV-optical imaging), STANCam (Standby CCD imager).
For details, see
The Italian community can request up to 16 (sixteen) nights on the basis of the exchange time agreement (see below).

Further important information for the proposal preparation is reported at

All proposals will be judged strictly on their scientific merit.



Large-Program and Long-Term proposals cannot be submitted answering the AOT40 call. In particular, a Long-Term program on the optical counterparts of gravitational wave events is already running at TNG. Therefore, proposals on this topic will not be accepted anymore. Moreover, objects included in the TNG Protected Target List ( cannot be requested.

The PIs of ongoing Large Programs are not requested to send a progress report in this call.
