Measurements of SOHO-2022 & SOHO-2024 in C3

I managed to measure Michal’s bright Kreutz group sungrazer SOHO-2022 and another sungrazer belonging to Marsden group SOHO-2024 detected by Rob both in C3 images. Here come my measurements:

I hav again failed to measure their C2 positions. Frankly speaking, as pointed out by Rainer, Astrometrica s not suitable to conduct such work as da plate constant s still too low for a C2 image, moreover, plentitude of noise points cause great interference to Astrometrica so that da software will find itself hard to indentify *truly real* reference stars even when they’v been manually aligned well with da stars in C2. Only by erasing da noise points one by one manually in some software, if da stars r bright enough in C2’s FOV, can Astrometrica solve da problem… Quite time-consuming certainly ><

Yet unluckily I don't get enough time at all to do all of these work as I'v been busily preoccupied with da comin GRE test diz year. I won't get enough time to interpolate da needed space vectors at d observed time either… So I juz leave simple measurements alone here. Once I turn available, hopefully I'l try to make further analysis if ther doesn't turn out to b too many comets.
