Delta Scorpii 2011 - Day 10, July 07

This message is being written while the last night is coming to the end and, probably, will only be finished when I get home.
We had 10 nights at the IAC80 and this one is the last.
Tomorrow is the trip back home and our flight leaves Los Rodeos, Tenerife North, at 13:20 local time.
As reported before, there are some personal equipments in use and the removal must be done by the competent personnel. We cannot do it.
They will be here tomorrow morning, after 09:00.
We shall meet them to take our belongings, pack them and rush to the airport.
Tonight, our only target will be Delta Scorpii, so that we can sleep for a while.
By the physical limitations of the telescope, the hour limit is 02:18 local time.
We make 3 series of 30 minutes in the helium II line, 30 minutes in the 4500 line and 30 minutes in the Halpha line, plus the correspondent calibration spectra, before and after every capture.
After the end of the captures, we must back up the data and complete all the procedures to park the telescope.
This means that the night today will end by 03:00.
That's what we did. And, by 09:00 the maintenance personnel quickly removed all our equipments.
We left the observatory at 09:40, stopped for a cake and a coffee in La Esperanza and went to the IAC, in La Laguna, to buy some pins, sweatshirts etc.
The flight from Tenerife to Madrid had a delay of almost 01:30 and we managed to catch the flight from Madrid to Lisboa just at the last minute.
After take off from Tenerife I took this photo.



It is a memory of 10 unforgettable nights.
