Fakta om SN 2020jfo h\u00e4r.\u00a0 <\/a><\/p>\n\n\n\n
Allt pekar p\u00e5 att vi r\u00f6r oss med en Typ II-sm\u00e4ll, det vill s\u00e4ga en “implosion-explosion” av en tung stj\u00e4rna. F\u00f6rst kollapsar den och sen kommer en v\u00e5ldsam rekyl.<\/p>\n\n\n\n
Jesper menar att sm\u00e4llen b\u00f6r kunna observeras h\u00e4r i Sk\u00e5ne eftersom Virgo\/Jungfrun st\u00e5r bra till sent p\u00e5 kv\u00e4llarna i syd. I samband med uppt\u00e4ckten dokumenterade italienarna <\/a>Nico Montigiani <\/strong>och Massimiliano Mannucci<\/strong>, knutna till Associazione Astrofili Fiorenini och Osservatorio Astronomico Margherita Hack, supernovan s\u00e5 h\u00e4r (magn 14,6 och stigande):<\/p>\n\n\n\n <\/p>\n\n\n Jesper ber\u00e4ttar ocks\u00e5 att Palomars stora 200-tummare \u00e4r inaktiverad just nu men kullens P48 och P60 \u00e4r ig\u00e5ng bevisligen. Och Keck med teleskopen p\u00e5 Hawaii \u00e4r p\u00e5 g\u00e5ng att starta upp igen.<\/p>\n\n\n\n N\u00e4r vi tittar p\u00e5 aktuella ekonomiska kurvor ser vi att det finns ett rej\u00e4lt hack ner\u00e5t just nu, detta tack vare coroneviruset. Samma hack – med undantag enligt ovan – kommer att kunna sk\u00f6njas i m\u00e4ngden “nya astronomiska observationer”. ESO i Chile har st\u00e4ngt ner. I Kalifornien \u00e4r, som v\u00e5r gamle ASTB:are Niklas Henricson<\/strong> d\u00e4rifr\u00e5n ber\u00e4ttar, alla observatorier under University of California-flaggan nerst\u00e4ngda.
