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. |
