&lt;hr /&gt;
&lt;div&gt;== Gaia Science Alerts Follow-up Server ==&lt;br /&gt;
We are currently testing a facility which allows for rough uniform calibration of the photometric follow-up observations of alerts reported by SkyAlert.org.&lt;br /&gt;
Please refer to the [[Media:GSAFSManual2011.pdf | Manual]] for details. If you plan to perform any photometric follow-up observations of the alerts available at SkyAlert.org and you would like to use our service, please contact [[User:Lukasz | Lukasz Wyrzykowski]] for password. When contacting us please provide us also with your observatory name, longitude and latitude and available filters.&lt;br /&gt;
&lt;br /&gt;
== Preliminary minimal requirements on the photometric and spectroscopic follow-up of Gaia Alerts ==&lt;br /&gt;
&lt;br /&gt;
'''Photometry:'''&lt;br /&gt;
&lt;br /&gt;
* multi-band photometry, at least two bands (e.g. V,I), Sloan ugriz preferred&lt;br /&gt;
* flux calibration no worse than 10% (0.1 mag)&lt;br /&gt;
* availability of flux measurements within less than couple of hours&lt;br /&gt;
&lt;br /&gt;
'''Spectroscopy:'''&lt;br /&gt;
&lt;br /&gt;
* spectral range minimal: 4500-7000A&lt;br /&gt;
* signal to noise &amp;gt; 20 all over the range above&lt;br /&gt;
* resolution R &amp;gt; 150&lt;br /&gt;
* lambda calibrations better -+ 3A&lt;br /&gt;
* relative flux calibrations better -+10%&lt;br /&gt;
* absolute flux calibrations: none&lt;br /&gt;
* availability of reduced spectra within less than 12h&lt;br /&gt;
&lt;br /&gt;

'''Please expand this list with information on the telescopes/surveys which might be suitable and interested in Gaia alerts follow-up and in operation in years 2012-2017.'''&lt;br /&gt;

&lt;br /&gt;
* MASTER Robotic Net ([http://arxiv.org/abs/0907.0827 Lipunov et al. 2009]) limiting mag= 19-20, started in 2002 in Moscow, Russia, followed-up many GCN alerts; now being upgraded to a network all over Russia (1000 clear nights per year).&lt;br /&gt;
&lt;br /&gt;
* 3 telescopes operated at the Konkoly Observatory, Piszkesteto Mountain Station [http://www.konkoly.hu/staff/racz/piszkesteto.html] (Hungary): 50 cm Cassegrain, 60/90/180 cm Schmidt, 1m RCC.&lt;br /&gt;
