7 years of PVOL
The Planetary Virtual Observatory and Laboratory (PVOL) is an online database of amateur images of the outer planets (Jupiter, Saturn, Uranus and Neptune). It was developed in early September 2004, during my attendance to the first NVO Summer School in Aspen (Co, USA). It was first put online during November 2004, so we already celebrated its 7th birthday.
After a bit more than 7 years online, it was time to prepare some charts showing the evolution in the number of images published. The following graph shows the number of images of Jupiter available since year 2000 (PVOL inherited the images already available in the previous IOPW page).
And the 2011-2012 apparition of Jupiter didn’t even finish yet!
So, thanks to the growing community of amateur astronomers (260 listed today) publishing images in the PVOL, and special thanks to the Planetary Sciences Group of the UPV-EHU for the great work they’re doing managing the system.
