C/2013 R1 (Lovejoy)

Post by Christopher K. » November 16th, 2013, 6:09 pm

Comet Lovejoy is putting on a very nice show at this time, at approximately magnitude 5.4. Terry Lovejoy discovered the object in September using a 20cm reflector and CCD camera. Gareth Williams calculates Lovejoy will reach perihelion on 25 December, between 12pm and 6pm CST.

Below are the times at which Lovejoy will reach forty-five degrees altitude in the Baton Rouge sky, together with some cautious magnitude estimates.
17 November: 3:30am / magnitude 5.4 [2˚10' NW of 46 Leonis Minoris]
18 November: 3:43am / magnitude 5.3 [0˚44' S of 51 Ursae Majoris]
19 November: 3:56am / magnitude 5.3 [1˚05' NE of 55 Ursae Majoris]
20 November: 4:11am / magnitude 5.2 [2˚44' E of 57 Ursae Majoris]

Well.... It seems Lovejoy is not brightening, really. It will remain at magnitude 5.3 through the 22nd, probably. I will attempt to view it in a few hours.

Below are the times at which Lovejoy will reach thirty degrees altitude in the Baton Rouge sky, together with magnitude estimates.
20 November: 2:50am / az 59˚ [2˚30' E of 57 Ursae Majoris]
21 November: 3:05am / az 57˚ [1˚57' S of 67 Ursae Majoris]
22 November: 3:20am / az 56˚ [0˚46' SW of 4 Canum Venaticorum]
23 November: 3:35am / az 56˚ [1˚41' N of 9 Canum Venaticorum]

Lovejoy is at about magnitude 4.8 and is expected to hold steady at that brightness throughout this week.

Below are the times at which Lovejoy will reach twenty degrees altitude in the Baton Rouge sky, together with magnitude estimates.
4 December: 4:51am / az 57˚ [1˚08' NE of Alkalurops]
5 December: 4:58am / az 58˚ [0˚44' N of Zeta2 Coronae Borealis]
6 December: 5:04am / az 59˚ [1˚14' NW of Kappa Coronae Borealis]
7 December: 5:10am / az 60˚ [0˚45' S of Kappa Coronae Borealis]

Damian Peach captured Lovejoy on 1 January as it passed through Hercules. On that morning Lovejoy would have been in darkest skies in Baton Rouge until 5:35am, only reaching nineteen degrees before twilight began.

The image was the 3 January APOD:

The bluish star below Lovejoy is probably the B-class, magnitude 5.5 star HIP85385. The orangish star to Lovejoy's upper left is probably the M-class, magnitude 6.8 star HIP85744.
