If we are limited on the wavelength range, is there a preferred coverage to observe? At the moment, I can only see 1400 Angs, and I would like to choose wisely, without doing it 3x to get the full visible spectrum..

Hallo Beobachter, INFO es soll eine SN mit bereits 11 mag aufgetreten sein. Auch für spektroskopische Beobachtung geeignet. http://www.cbat.eps.harvard.edu/unconf/ ... 40260.html |

Meine Zusammenfassung zum Stand der Dinge: - Supernova in M 82 ist bereits 11,7mag hell Kurz gesagt: Die wird sicherlich heller als 2011fe in M 101 und wenn alles passt, dann könnte sie sogar heller als 9,0mag werden. |

Hi Nico, I estimated to start with that it might reach 8.5 but the sn actually exploded ~15th January and for some reason was missed by everyone for 6 days. http://www.k-itagaki.jp/psn-m82.jpg That means it has already been rising for 6 days. Also the spectra show strong interstellar extinction http://www.spectro-aras.com/forum/viewt ... ?f=5&t=766 so we might have to wait and see how bright it gets Cheers Robin |

Yesterday I hope about a brighter than 9.0 mag Supernova, now I think about a 10.5 mag bright maximum. Too bad. |

Hello Filipe, Zitat: If we are limited on the wavelength range, is there a preferred coverage to observe? At the moment, I can only see 1400 Angs, and I would like to choose wisely, without doing it 3x to get the full visible spectrum..
As the SiII line around 6150Angs. might be expected the most prominent feature in the spectrum, I would prefer this region.You will get an overview from current spectra and may compare with one of my results from 2011, Supernova in M101.  Regards, Torsten |
