Follow-up

Gaia Science Alerts Follow-up Server

We are currently testing a facility which allows for rough uniform calibration of the photometric follow-up observations of alerts reported by SkyAlert.org. Please refer to the 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 Lukasz Wyrzykowski for password.

Preliminary minimal requirements on the photometric and spectroscopic follow-up of Gaia Alerts

Photometry:

• multi-band photometry, at least two bands (e.g. V,I), Sloan ugriz preferred
• flux calibration no worse than 10% (0.1 mag)
• availability of flux measurements within less than couple of hours

Spectroscopy:

• spectral range minimal: 4500-7000A
• signal to noise > 20 all over the range above
• resolution R > 150
• lambda calibrations better -+ 3A
• relative flux calibrations better -+10%
• absolute flux calibrations: none
• availability of reduced spectra within less than 12h

Current and future instruments suitable for Gaia alerts response

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.

Hessman's list of (mainly robotic) telescopes (including ones in preparation).

• MASTER Robotic Net (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).

• 3 telescopes operated at the Konkoly Observatory, Piszkesteto Mountain Station [1] (Hungary): 50 cm Cassegrain, 60/90/180 cm Schmidt, 1m RCC.
