The Karin Family is a small group of asteorids, with 832 Karin being the primary body. This family, discovered by David Nesvorny and William F. Bottke at the Southwest Research Institute, is believed to have been created approximately 5-6MY ago by the collision of an asteroid with a 15km parent body, making it one of the youngest families known.
For this reason, the members of the group deserve particular attention in order to study the early stages of an asteroid family's evolution. Of particular interest are lightcurves to determine if one or more members are tumbling and the spin rate for each. These curves can be combined with those obtained in later years to see what effect, if any, YORP has had on the family members.
If you obtain lightcurves of any of these objects, you should post the results on the CALL site, publish a paper somewhere (the Minor Planet Bulletin is an excellent journal for amateur efforts), and contact the authors above.
This form generates a list of the currently known Karin family members, giving the date/magnitude/declination the asteroid is brightest in the current year, along with the magnitude/decliation/rise/set local standard times. Most of the members are usually fainter than most amateurs can work. However, some do occasionally come within reach of larger amateur and moderately-sized institutional instruments.
If your equipment allows, (B)VRI work would be greatly beneficial in addition to period/amplitude analyis of the lightcurve.
Enter Longitude and Latitude to the nearest whole degree.
Western/Southern Hemisphere = negative
(For example: Florissant, CO = 106 +39; Adelaide, Australia = +138 34)
Enter Elevation above sea level in meters (1 foot = 0.3048m)
If invalid entries are made for Longitude and/or Latitude, geocentric positions are returned
In the table that is returned, if the rise and/or set time is 00:00, that means the object does not rise and/or set on the current date. Depending on the declination and your latititude, this could mean the object is near your pole and so circumpolar or too near the opposite pole and so always below the horizon.
The positions are not perturbed but are based on relatively recent elements. You should generate a more accurate ephemeris if you plan to work a given asteroid.
It takes, on averge, three to five seconds for the data to be generated. Please allow for that plus the download time.
