First snow of the season at Pico del Teide Observatory (PTO)

Last Monday December 2 we suffered the first episode of copious rains this autumn in Izaña. Although we recorded some more than 25 mm, temperatures were relatively high (between 4 and 8 ° C), so we will have to wait for the next few weeks to see snow in our Observatory. However, at the satellite station Pico del Teide (PTO), located in Terminal cable car station ( at 3,555 m above sea level, it snowed with temperatures ranging from 0° and -2 ° C, and with moderate winds between 30 and 80 km/h, leaving nice winter pictures. The pressure ranged from 658.9 hPa to 656.1 hPa. For some instruments, such as the Cimel sunphotometers, it was the first experience in winter conditions at so high altitude, and it seems that they did not suffer any damage.
