GREGOR Observing plan 2019 (updated Jun 23, 2019):





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. Anybody apart from the operator of each telescope can apply for observing time (e.g. KIS cannot apply for GREGOR or VTT time). Contact Dan Kiselman or Lucia Kleint 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.


A total of 40 days (GREGOR) or 20 days (VTT) are available for SOLARNET observers in 2019. 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.
