telescopes are inherently inflexible • Small telescopes can be easily operated more flexibly • There are various scientific/institutional reasons not to dedicate small telescope resources to a particular project • “All” one needs is to be able to pool resources January 9, 2014 LOFAR Transient Mee9ng 2

(longer than one thinks) to get any system running, much less a heterogeneous one • Career paths of major players are relevant • “Simpler” networks are already very complicated • API != implementation and one person’s particular implementation may not be another’s • Good science drivers are needed to overcome the sociological/institutional inertia January 9, 2014 LOFAR Transient Mee9ng 7
Many on-going surveys (OGLE, CSS, CRTS, PTF, Pan-STARRS, LOFAR, GAIA, …) need follow-ups • Las Cumbres Observatory • Many new “minor” players with resources and potential interest • Need to create and exercise now the infrastructure needed tomorrow by even bigger surveys like LSST, SKA, … January 9, 2014 LOFAR Transient Mee9ng 8 potental networked science thorny problems HTN
resources without cumbersome institutional politics – the software to make participation “easy” is available What might prevent/stop a HTN effort? – science goals not well-defined enough? – too much heterogeneity? – too little heterogeneity? – too little benefit for the effort? – quality control?

help make any telescope (manual, remote, robotic) principally VOEvent- aware and HTN-compatible with a “minimum of effort” • Encourage the creation of science-driven consortia to operate VOEvent-driven and HTN-connected networks January 9, 2014 LOFAR Transient Mee9ng 10
an open-source HTN- client with – an absolute minimum level of complexity (use & installation) – transport exactly like VOEvent – example of manual and automatic interfaces practically “out of the box” – some help in interfacing (e.g. simple mapping of schemata) – configurable for multiple consortia – define minimum standards of client calibration/participation • Create an open-source HTN-Server to foster creation of consortia January 9, 2014 LOFAR Transient Mee9ng 11
of its time • Things have changed/progressed • We need to respond now to the “follow-up crisis” • The sociological/institutional compunctions against joining a heterogeneous network can be overcome • We just need to make it easy to join one or more networks by providing standard tools and simple implementations January 9, 2014 LOFAR Transient Mee9ng 12
