The MONSOON development program continues and we report on the current status of, and the future plans for this project.
The Forecast : Warm deluges of success with some cold showers of reality
Not enough time to catch all the photons we need !
Big instruments – Big focal planes
More photons !! UV – VIS – NIR – MIR.
MONSOON designed to accommodate these requirements
So; where is MONSOON ?

Open Source Release – November 2004
This is an Open License Agreement that allows you access to the complete technical information available for MONSOON. You must, for legal peace of mind, agree to the terms of this license.
Essentially, by clicking the "Accept" button at the foot of this page, you agree to make any contributions you may make to the MONSOON technology available to others without hindrance and surrender all rights to patent claims to any of the covered technology - including the original source.
In addition, the license explicitly absolves NOAO from any warranty or liability for the use of, or fitness of purpose for, MONSOON technology.
The good news is that the license doesn't stop you from using (or abusing) the technology, or building systems from the information, or even making a dollar from supplying this technology to others. In fact you are encouraged to do all of these things !

- Collaboration History -
Cold shower #2: - Each ‘collaboration’ effort requires explicit support which in turn, requires resources.
However, collaborations that ‘stick’ are very productive !
& IN SERVICE
Requirements established May 2002
+ 11 OTHERS
Requirements established March 2004
1). Replace unreliable, high maintenance, or obsolete CCD controllers.
2). Unify detector controller architectures to reduce maintenance burden.
3). Apply to new instrumentation without risk of ‘single source’ components.
Requirements established February 2005
So happy we could sing about it !!
All together now …
The last word: An opportunity to take a MONSOON together !
