M44 and Photometry of the asteroid 6774 Vladheinrich

6774 Vladheinrich / Main belt asteroid

Distance 1.02 AU
3.6 km diameter
orbital period 3.25 years
orbital speed : 22.0km/s
Magnitude: 16.6
Movement 40.5"/h
The fluctuation in the magnitude is about 1mag
There is no information about the rotation period.

Rev D shows the movement of 3 hours and the light curve of the Asteroid 6774 Vladheinrich, captured on 2022.02.12.
Camera : ASI174mm / 30nm Ha filter
Exp time 3 hours (90 x 2 minutes)
The Moon was very bright and near, I had to use the 30nm Ha filter.
Fortunately I could do photometry despite the bright Moon.
Of course this is not optimal, but the light curve is pretty similar to the light curve I obtained a week ago. It looks like that the rotation period is about 2 hours. For a more precise value I need another data set. I will capture the asteroid again when the Moon is gone. I hope that under moonless conditions I get a more accurate lightcurve.🙂

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
