Updated the entry for
PSN J05164155+0629302 (Type Ia)
and noticed that LSQ11pn
and PSN J05164155+0629302 were within 1 arc second of eachother,
so I combinded the two entries, also the host galaxy is not the one listed
on TOCP, that was also corrected.

Arhived several older objects.
The page was just getting too long.
Note that the format of the
archive for 2011 has changed
from previous years. I keep the CBAT named SN in alphabetical order, but
those which are unnamed are "roughly" sorted by date.
2011/11/22
Updated the entries for

Sounds like Dan got through his backlog....
Does anybody know of a grant that I could apply for to support this page?
I probably spend about 2 hours a night working on it.
2011/11/17
Updated entries for
2011ht
(= PSN J10081059+5150570, our bright LBV is now officially a supernova)

could confirm it),
2011hj
(was PSN J18322232+6653466, Type II) and
PSN J02184584-0638304 (Type Ia)
Archived several
older SNe. Moved
PSN J00445527+0044552
(aka asteroid 372 Palma passing in front of M31) into the
Boneyard
as it has already caused way too many heart attacks.
Updated the entries for

(Type IIP as previously noted, was PSN J19542142-5842390),
2011gw
(Type Ib/c as previously noted, was PSN J07281702-6221189),

Nova M31 2011-10a? (Fe IIb nova, = PNV J00425701+4117095)
Format change
From now on the "Mag" entry will look like this:
"Mag 15.5:7/8".
Which will read "Magnitued 15.5, last observed on 7/8/2011".
Note that the magnitude listed need not be the magnitude when last observed
if no magnitude was reported.
You will also notice that the "All active SN" list is much smaller.
It is now driven by these entries.

(was PSN J19065017-6141577, Type Ia in IC 4815)
The page was getting too long, so I

2011/08/31
Created an entry for

Created an entries for
PSN J00471993+2749355 (Mag 18.1 in IC 1584) and
PTF11kly
(Mag 17.1 Type Ia in M101,
since this will soon be in solar conjunction, get it now!)
Updated the entry for
2011fd
(was PSN J06463985+6021028, Type IIP in NGC 2273B, but nothing on

Updated the entry for
2011dz
(was PTF11dxu, PSN J16124482+2817032, now an older Type Ia in UGC 10273
(note that there is no mention of the PTF discovery in the CBET))
Sharp eyed web page readers will notice that the "All Active SN" and
supernova count have been updated for the first time in 2 weeks. These entries
are normally maintained by a program that I just got working again.
Updated the entries for
2011dt
(was PSN J14243612+3516387, Type II in UGC 9233),

Nova M31 2011-06c? (Swift observations, got up to Mag 15.7,
now faded out, brightest nova observed in M31 by swift)
Yes, I'm still on vacation, and not with the relatives while I update
the web page via my brother in law's wireless connection.
My laptop works better than his compter, so it gets some use, like looking
up Petskey stones.
As I said last night, I'm taking off to Traverse City, Michigan
for 4 days, so watch the Messier galaxies. Major discoveries tend to happen
when I'm away from my computer.
I'm taking another short vacation (4 days this time to Michigan),
so watch the Messier galaxies! Stastics has it that major discoveries
happen when I am away from my computers...
2011/06/08
Created a full entry for
PTF11dxu (Mag 15.0 in UGC 10273)
Created a
2011dh images sub-page.
I added a series of images from Lode Stevens almost capturing the moment
of this explosion. Finally got through my backlog.
2011/06/04
Updated the entry for
2011di
(was PSN J18435900-6159460, Mag 14 in IC 4754)
Created entries for the two new supernovae.
I have yet to load the discoveries from
ATEL 3403
Updated the entry for
2011dh
(was PSN J13303600+4706330 in M51)
Too tired to do anything else. Still at hotel in NYC.
Added several images of
2011dh
I have added all of the links that people have given me,
but if you sent me an image
it will have to wait until I get home so that I can process it.
At this point I have a backlog of at least 10, with a few prediscoveries.
2011/06/03
Quick, from the road update. Just had to post the new
Possible supernova in M51
and two others. I also posted a reference image of this new SN. I have
several others to post, but I have to go on a school trip with my son.
Format change.
The Transient Objects Confirmation page has changed the way
followup observations are archived. Now every object has a
sub-page where followups are stored.
SO: All of the "TOCP" links now point directly to the followup subpage,
with the exception of dimmer supernova, which have a link at the end of the
entry.
Updated the entries for
2011cg (was CSS110414:145909+071804, Type Ia,
Mag 15.7 in anonymous)
2011ch (was CSS110427:130254+495229, Type Ia) and
2011ci (was PSN J10180041-0232414, Type Ia)
Errata: Odd Trondal noticed that the host galaxy of
PSN J16334944+3915487 is, as announced, IC 4612.
2011/04/19
Created the entry for
2011br
(Type Ib, was PSN J15062020+6259006)
Joe Brimacombe noticed that the entry I had created for
SSS110408:095830-105315 was actually a duplicate of
2011R
(Errata: note that I had this marked as a Type Ia, the original
data I was give says Type II (which agrees with 2011R). My mistake)
The "All active SN" list is now automatically updated with a program,
so it should be alway up to date. Slight format change. * means more the
last observation is > 30 days old. ** means the last observation is >
60 days old.
2011/04/14
Updated the entry for
2011bp
(Type Ib, was PSN J11122996+3123055)

2011bo
(was PSN J18593846-4145558 in ESO 337-6, Type Ic)
Nights like this I have to put in a few hours to update the page.
Enrico Prosperi sent me 25 images. I also loaded new discoveries from
LOSS
and CHASE.

(Mag 17.0 in IC 1277, same galaxy as
2006gz)
Updated the entry for
PSN J08425627-2003112
(Stu Parker, who found it, said that it wasn't there when he tried to confirm
it, BTW, Stu was effected by the New Zealand earthquake)
After seeing
ATEL 3164
I thought that we had a new Mag 13 supernova.
I pubished this data on
TOC page.
When building the entry, my scripts told me that I had just redone the
entry for
2011aa.
Updated the entries for
2011X

(was PSN J00325124+1144075, Type II)
Format change:
the "R.A. Decl." link on the latest two supernova
(PSN J13304304-2057140)
are slightly different.
If this causes a problem, please let me know.
Updated the entries for
2011I
(was PSN J09502499-2151451, Type Ia)
2011J
(was PSN J10504420+2800490, Type Ia, made a full entry for it) and
2011K
(was PSN J04453038-0720527, Mag 15.0 Type Ia on the rise)
Updated the entry for
MASTER OT 013241.20+343809.1
(= CSS101210:013241+343809, found last month, probably a cataclysmic variable)
and
PTF10aavz
(EVLA observations)
Created entries for
2010lr
(Mag 17.9 in anonymous),
2010ls
(Mag 16.2 Type IIb near PGC 3085578), and
Nova NGC 7248 12a
(= PTF10acbp, Mag 19.9, spectroscopically confirmed)
Updated the entries for
2010ll
(Type Ia),
2010lp
(Type Ia), and
2010lq
(Type Ia on the rise, was Possible supernova near ESO 495-16)
2011/10/06: Noticed that the icon for
MASTER PGC1375631 looked suspiciously like
2011ft (fixed)
2011/04/20: Odd Trondal noticed that the host galaxy of
PSN J16334944+3915487 is, as announced, IC 4612.
2011/04/19: Joe Brimacombe noticed that the entry I had created for
SSS110408:095830-105315 was actually a duplicate of
2011R
(Errata: note that I had this marked as a Type Ia, the original
data I was give says Type II (which agrees with 2011R). My mistake)
2011/02/27: The discovery image of
PSN J14290502+4154427 (later 2011ai) was incorrect.
Error persisted for 2 days.
