NAMES OF STARS FROM THE PERIOD OF THE VEDAS
Figure 6 shows 35 degrees containing four Nakshatras in Kanya Raashi called Uttara Phalguni, Hastaa, Chitra, and Swati.
Though Uttara is a part of Virgo/Kanya in the zodiac, in Bharateeya measure it is considered as a part of Tula. All the Kanyaa Nakshatras are in the Moon Band and are the brighter stars of the Raashi. Uttara Phalguni or Uttara is onsidered to be a lunar mansion of 2 stars. The following table provides a list of two stars, which can qualify as Uttara Phalguni from a brightness point of view, location with reference to moon traverse band, and distance from previous Nakshatra.

Both the stars are at same time distance from Poorva Phalguni. If a single star has to be identified as Uttara Phalguni, then 94 b Leo/SAO 119076 / HD 102870 is the best candidate, despite Denebola being brighter. Reason is that Denebola is about 5 diameters out of Moon traverse band while Zavijava is in the moon traverse band. Uttara Phalguni, is also called Zavijava by Arabs.
Hastaa is considered to be a lunar mansion of 3 stars. The following table provides, a list of three stars which can qualify as Hastaa from a brightness point of view, location with reference to moon traverse band, and distance from previous Nakshatra. Hastaa has also been called Porrima, probably an Arab name.

Chitra is 50 minutes or 13.3 degrees (E-W) away from 'Hastaa'. There can be no doubt about the identity of Chitra. It also stands for the name of the first month in Chandramaana calender. The Bhrateeya Chandramaana Ugadi (new Year day) is on the new moon day of this month, and this day is very near the Spring Equinox day. In Raashi/Nakshatra translation, 1/4 of Uttara-Phalguni is considered as belonging to Karkataka. 3/4 of Uttara-Phalguni, whole of Hastaa and 1/2 of Chitra are considered to belong to Kanyaa Rashi. The other half of Chitra is shown as Tula Raashi.
This star which is very near the ecliptic was scientifically studied by Hipparchus in 150 BC and by Ptolemy in 150 AD, and they noticed the property of earth's precession using observations on Spica.
