Updated graphs for V442 And using several spectra from BeSS (thanks to all observers!).

Hello, here is an update on V442 And outburst which started between sep 30th and october 5th. Emission is still growing: 20191027 Graphe V442 And.JPG 20191027 Graphes V442 And.JPG Discovery spectrum on my blog: https://observatoire-belle-etoile.blogspot.com/2019/10/v442-and-again-again-again-in-outb...

PS: note that we manually validate ALL spectra in BeSS database. There is currently an average of 11 spectra submitted every day (114 if you count all echelle spectra orders)... :-) As Valérie mentionned, there is a FaceBook private group for Be star observers (just need to be on facebook, have at l...

Hello, I am one of BeSS validator and we are almost up to date in our validation process. BeSS validated spectra are visible on the next day (around 01h00 UT). As a Be star observer (and actually only observing Be stars with my backyard setup), I have added the priority >1 TESS target in my target l...

Hello, you may remeber that V442 And went into outburst in august last year. Well... it did it again! I have been following it since june (33 spectra!) without significant changes - but still some small variation to study later in more details. My spectrum from august 11th was in absorption, then on...

Hello, thank you to all of you that are currently participating to this campaign. It has been interesting for the last few days as we noticed some evolution on lam Cyg and of course this brought some excitements: Capture.JPG We of course alerted the team that initiated this campaign but it turned ou...

Hello, here a request rom a professional astronomers team to monitor three taregt with the goal to trigger follow up observations with different instruments in case of discovered outburst: We would like to request one spectrum per night to be taken for each of the 3 targets at resolution at least 10...

superbe!

Hello Michael, VV Cep spectra are archived on ARAS database there: http://www.astrosurf.com/aras/Aras_DataBase/VVCepStars/VVCep.htm If you are interested to include yours as well, please send them in FITS file format (compliant with BeSS format) to my email thizy@free.fr and I'll include them. Cordi...

Fallait oser Hubert - bravo pour ce superbe résultat!
