After a few days, we imaged the intriguing (457175) 2008 GO98, the Hilda-type object again, to check if its cometary activity was still ongoing. And it was, of course, as this image clearly. The...
We managed to capture new images of (457175) 2008 GO98, the Hilda-type asteroid recently turned comet. It still show a little coma, so the activity is still ongoing. The image above is the average...
Earlier this month, the Hilda-type asteroid (457175) 2008 GO98 showed evident cometary activity on images captured by G. J. Leonard at Mt. Lemmon Survey.The following nights the extremely bright full Moon was a serious issue, making...
As you may have heard, comet C/2015 ER61 Panstarrs has recently experienced a nucleus splitting. We were among those who reported this event. Digging in our image archives, we have found evidence of that...
After our independent observations of the nucleus splitting of comet C/2015 ER61, we managed to do some further observations. The “b” fragment was still easy to see and we are pleased to show our...
During our last observation of comet C/2015 ER61 Panstarrs we spotted an apparent fragment. We did send these info to both the Minor Planet Center and the Central Bureau for Astronomical Telegrams and the...
In a few days, the Earth will cross the orbital plane of comet C/2015 V2 Johnson. This geometric condition makes possible to see a dusty feature named “anti-tail”, apparently pointing to the Sun, where...
Comet C/2015 ER61 Panstarrs was imaged again a few nights ago and it showed a beautiful ion tail. It is one of the most beautiful comets we see so far this year. The...
After more than one month, we looked for comet 45P/Honda-Mrkos-Pajdusakova again, knowing it is now no more than a ghost of itself, after its glorious days, many weeks ago. But the sky awarded us with...
Despite the extreme observing conditions, we could capture comet C/2017 E4 Lovejoy again, obtaining a precious documentation of its fate. The image above comes from the sigma clipping combination of six, 60-seconds exposures, unfiltered, remotely...
Comet C/2015 V2 Johnson is on its way to perihelion, which it will reach next 12 June. For many weeks, this comet, while relatively bright, showed only a dusty tail, but now it proudly...
While observing conditions are, day after day, more difficult because of its small solar elongation, we continue to observe comet C/2017 E4 Lovejoy while its fades, after its nucleus disintegrated. The image above comes from the...
Comet C/2017 E4 Lovejoy was imaged again, the day after its perihelion. It continues to fade, while dissolving, also being more difficult to see, because of the decreasing solar elongation. The image above comes from...
At last, comet C/2017 E4 Lovejoy reached its perihelion on 23 Apr. 2017 at 07:26 UT. Four hours later, we captured this image while it was only 6 degrees high, above the NE horizon. The...
