After the meeting, the IAC had organised a trip to the Observatorio del Teide. We headed up there in a little minibus and it was a lot like the Observatorio del Roque de los Muchachos on La Palma in that the driver drove too fast on the winding road and I got to the top feeling like I was going to die of carsickness.
It was a calm and warm day. One of the observatory technicians was looking at the Sun through one of the telescopes so we had a look too, and saw a group of sunspots. The sun had been unusually inactive for quite a while so we were quite lucky not to see just a blank surface.
Looking around I could see a couple of other islands across the sea in the hazy distance. Apparently, ancient island legends tell of a mysterious eighth island which can sometimes be seen across the waters but never reached. I could only see real islands today.
Back in La Laguna I thought I had an easy and relaxing journey home. But an hour and a half before my flight, I realised it was going not from nearby Tenerife North airport, but Tenerife South, 50 miles away at the other end of the island. I leapt into a taxi and sped off. I picked a good driver, we made excellent time and in the end I easily made the flight. Next time I'm here, though, I'll check my bookings a bit more carefully.
