Explanation of Alerts table
Alert ID: The name that was assigned to this Alert. Click on the link to see more information about the Alert.
Time: When Gaia first detected this Alert.
RA: The right ascension of the Alert (see Observing advice for more info).
Dec: The declination of the Alert.
Mag: The brightness of the Alert in Gaia magnitudes. For more information on magnitudes, see Observing advice. Note that a lower value for the magnitude means an Alert is brighter, and a higher value means it is fainter.
Classification: What sort of transient each Alert is.
Comment: Any additional information we have about why an alert is interesting, or information such as its distance.
Desired follow-up: Guidelines on what data we need from telescopes such as Faulkes for each Alert.
School: Initials of schools following-up this Alert (see Schools following-up Gaia Alerts).

|Gaia16ajr||30 Mar 2016, 18:22||88.24821||-17.86224||16.87||unknown||Candidate SN||
This Alert isn't visible any more (as it is behind the Sun)
|Gaia16bef||30 Aug 2016, 23:09||203.66082||-23.68151||15.21||SN Ia||confirmed SN Ia, found by ASAS: SN 2016eiy||
This is a bright Type Ia supernovae in a nearby galaxy! See if you can get some imaging of it - try ugri imaging every two nights, it's currently mag~16
|Gaia16agf||27 Feb 2016, 06:41||98.53741||-25.18462||17.03||SN Ia||Candidate SN, GSTEC predicts young SN Ia at -16 days||ECS|
|Gaia16aza||6 Aug 2016, 19:25||245.35763||-26.77503||14.98||unknown||bright blue hostless transient||
Our best guess is that this is a new Cataclsymic Variable. It's quite bright at 15th magnitude, and we request monitoring in blue and red filters (e.g. g and r). A spectrum would be great so we can try to understand if it's really a CV, or something even more exotic.
|Gaia18aen||17 Jan 2018, 04:16||120.71694||-30.31032||11.33||unknown||bright emission line star in Galactic plane brightens by 1 magnitude||
This is bright and in reach of modest telescopes - BUT only really observable from the Southern Hemisphere. We've no idea what this is - please monitor
|Gaia17bej||7 May 2017, 14:30||274.25440||-31.38352||14.60||ULENS||source towards Galactic Bulge brightens by 3 mags, candidate microlensing event||
Candidate microlensing event... or is it? We don't know. Observe it to help us find out!
|Gaia17bnk||13 Jun 2017, 01:14||95.65247||-38.56183||17.46||CV||Candidate CV, 2mag rise in UV source GALEXASC J062236.61-383342.9, Gaia & CRTS have prior outbursts||
We think this is a cataclysmic variable and we want to measure its orbital period. Continuous monitoring for 2 - 3 hours in a single filter (e.g. g or r) will show how the brightness varies with time and from that we can work out the binary period.
|Gaia16afe||21 Feb 2016, 12:31||91.78404||-45.18118||18.86||SN I-pec||SN candidate offset from galaxy ESO 254- G 019 (z=0.038917) by 18 arcsec||
This was a peculiar thermonuclear supernova which is very far from its host galaxy.
|Gaia16bgk||11 Sep 2016, 16:21||310.16636||-54.31064||14.15||SN Ia||candidate SN in NGC 6942 GS-TEC predicts SN Ia||
This is a nice nearby Type Ia SN, and it's bright too - mag~14.5. You should be able to spot this with a small telescope and a CCD camera.
|Gaia18aod||8 Mar 2018, 09:11||208.36495||-67.41694||6.77||Nova||confirmed Galactic Nova, extremely bright, aka Nova Circini 2018 (PNV J13532700-6725110)||
An opportunity to observe a really bright Galactic Nova.
