Updated the entries for
2012if
(was PSN J11173029+5124074, Type Ia in PGC 34479 as previously noted),

Found that I had to use the "search" function to find a recent object.
So, I created a Sorted by name page so
that I could find things more easily.
Added this to the Archives.

Sharp eyed people will note that the "All Active SN" list now is a bit
longer and is sorted differently.   This list is now generated by a new
program I wrote that is much more thorough.   The list is first sorted by
RA, then by magnitude, with a 17.0 Mag cutoff.

Errata: Noticed that the script I have that adds "wikisky" links to the
list type entries has a flaw in the RA calculation. As a result I didn't
know that PTF11kju was found in
NGC 1144. All wikisky links have now been recalculated.

2012D
(was PSN J12583711+2710252, Type IIP)
MASTER OT061730.02+3540.6 (Type CV (variable star))
Created an entry for
PSN J05201494-2518563 (Mag 16.7 in IC 411,
NOTE the announced host was IC 441, but the new object's location,
and confirmation show IC 411)
SN Primo is being dubbed by NASA as the farthest supernova found, but I
can find no location or magnituded information, just a "bubble gum" press
release
Updated the entries for
2012A
(was PSN J10250739+1709146 in NGC 3239, Type II),
2011jn
(same galaxy as ROTSE3 J125708.9-172527), and
2011jq
(was PSN J05164155+0629302)
Updated entries for
2011js
(was PSN J02480496-1357511, Type IIn in NGC 1103),
2011jt
(was PSN J14532301+0257431, Type Ia),
2011jx
(was PSN J10290876+4604576, Mag 17.7 Type Ia), and
Nova M31 2012-01a? (= PTF12js, Fe II Extragalactic nova,
note that this object is very close to the Fe II M31 nova
Nova M31 2011-07b?)
2012/07/20: Had the RA of
2012do
(= CSS120620:135635+044652) as 12 hours, when it should be 13 hours.
Error persisted for 24 hours.
Joseph Brimacombe followed the location, and got nothing but empty space.
2012/01/31: Had the type of
2012L listed as a type II, when
(if I had the correct CBET linked) it is really a Type Ia.
2012/01/21:
Noticed that there was a 50% chance of the RA being off by 1/100 of an arc
second or the Declination being off by 1/10 or a second due to a rounding
issue.
2012/01/15:
Noticed that the script I have that adds "wikisky" links to the
list type entries has a flaw in the RA calculation. As a result I didn't
know that PTF11kju was found in
NGC 1144. All wikisky links have now been recalculated.
