Observing Season and applications for observing time

General Info

We have carried out a major redesign of the GREGOR optical setup. 2020A is the commissioning and science verification phase, during which we carry out joint observations with data sharing. The preliminary schedule to start observing in May had to be delayed due to COVID-19. GREGOR was aligned in July and commissioning started on July 30. The general plan is:

- 1 month (Jul 30-Aug 28):  technical commissioning by KIS.

- 1.5 months (Aug 29-Oct 8): science verification jointly by KIS, IAC, AIP.

Special rules concerning co_authorship apply to 2020A:

Publications: All data can be used freely. We expect everybody to follow good scientific practice (=include everybody who contributed significantly). Because of the large effort for the redesign and the implementation, T. Berkefeld and L. Kleint shall be included as Co-authors (unless they wish not to be on the paper) on any paper resulting from data taken during the science verification and commissioning phase. 

 

These rules do not apply for the 2020B observing which will be carried out in "regular" PI mode.

 

 

SOLARNET/CCI ITP 2020B:
SOLARNET/CCI ITP proposals are invited for the 2020B phase. Please use the proposal template below to apply for observing time and note that the proposal deadline is September 19.

 

Depending on the COVID-19 situation the PI will be able to conduct observations at the observatory on Tenerife with support of assistants present there, or at KIS in Freiburg with assistants supporting the PI at KIS.

Required acknowledgement and citations: 

The 1.5-meter GREGOR solar telescope was built by a German consortium under the leadership of the Leibniz-Institute for Solar Physics (KIS) in Freiburg with the Leibniz Institute for Astrophysics Potsdam, the Institute for Astrophysics Göttingen, and the Max Planck Institute for Solar System Research in Göttingen as partners, and with contributions by the Instituto de Astrofísica de Canarias and the Astronomical Institute of the Academy of Sciences of the Czech Republic. The redesign of the GREGOR AO and instrument distribution optics was carried out by KIS whose technical staff is gratefully acknowledged.

Options for telescope access

CCI international time program (ITP):

5% of the telescope time are reserved for international access to all solar telescopes on the Canary Islands (GREGOR, VTT, THEMIS). The observing time is assigned by the EAST TAC. For ITP time, applications must include researchers with affiliations in at least two of the following countries: Spain, UK, Germany, France, Italy, Finland. Contact Dan Kiselman for more information.

Spanish time (solar CAT)

See www.iac.es/OOCC/solar-cat/ for more information. According to international agreements, 20% of the observing time is reserved for assignment by the Spanish solar CAT. Presently, there are no restrictions on nationality to apply for GREGOR and VTT time through the solar CAT.

SOLARNET time

A total of 40 days (GREGOR) or 20 days (VTT) are available for SOLARNET observers in 2020. The observing time is assigned by the EAST TAC.

German time

(split 20%/20%/60% between the AIPMPS, and KIS, leading to effective observing times of 15%/15%/45% of the total available time). Each institute has guaranteed observing time at GREGOR and VTT. KIS decided to open their observing time with no restriction on nationality/institute provided that at least one Co-I on the observing proposal is from KIS. Contact tac@leibniz-kis.de for more information.
