here i will try to provide my own interpretation on the asteroid :p i am not a professional astrologer so take everything with a grain of salt.
vulcan is the Roman god of fire and destruction. he was the second son of jupiter and juno and the husband of venus. sometimes, he would be summoned to calm down fires. he was the father of caeculus, founder of Praeneste. his greek equivalent is hephaestus. he is considered the god of oven trade, arms, jewelry, metalworking.
he plots revenge against his mother, crafting her a deceitful golden throne. he did that because she exiled him for being born ugly. after being thrown off from mount olympus, he landed into the ocean, where he was raised by a sea nymph, thetis. his interest for fire and metalworking happened there.
during his adventures under the sea, he found the remains of a fisherman's fire, thus an unextinguished coal fascinated him, as it was still glowing. he took this coal to his grotto and made a fire with it. in the second day after he ignited it, he noticed that ”certain stones sweated iron/silver/gold.” in the third day the cooled metal was formed into jewelry.
one day, vulcan's foster mother left the grotto to attend a dinner party in mount olympus, wearing a necklace that vulcan made for her. ultimately, she got noticed by juno, who asked where was the necklace from. having thetis' reaction, juno became suspicious and later she realised how her son became a blacksmith.
so, what could this mean in a chart?
IN MY OPINION it may refer to places where you are forced to work on under pressure of heavy emotions. it refers to places where you have to work on your own and with some support outside of your family. in can refer to places where you may feel abandoned and where you fear abandonment, even places that caused such fears. surely, it represents areas of life that causes most trauma for you and parts of yourself that you are forced to transform, but it is for the greater good because once those purified, you will meet so much prosperity based on the placement of the asteroid.
ARIES/1ST HOUSE
1, 13, 25°.
you may have had a lot of transformative experiences regarding your image, and the way you act. depending on how the 1st house behaves in your chart, you are forced to do whatever it takes to achieve your purpose and to make yourself heard. if any planets are in the first house, you are forced to work on any hardships caused by those planets.
TAURUS/2ND HOUSE
2, 14, 26°
if you have vulcan in this placement, i feel like you might have gone through narcissistic abuse. someone might have been overly possesive towards you. if you are a woman and this asteroid is in afflicted aspect (square, opposition and even semisquare) to neptune/saturn/jupiter, i feel like you might have suffered a lot because you had a lot of expectations upon you.
GEMINI/3RD HOUSE
3, 15, 27°
you might have had a lot of conflicts in your near environment. you might have been bullied a lot in school and maybe by your neighbours. you might have been mocked for the way of your speaking. however, over time, you might become a master communicator and might have a job in areas relating to communication.
CANCER/4TH HOUSE
4, 16, 28°
might have had an absent mother figure. a lot of pressure in the family and might have suffered because of people who have extreme views about homeland. because you suffered in your family, you might have had tendencies to plot revenge against them. your mother figure might have not supported you in pursuing your dreams. could grow bitter over mother.
LEO/5TH HOUSE
5, 17, 29°.
you could be a pretty isolated individual. you are a very creative individual but any creative endeavor of yours might have been shamed on. might have been bullied as a kid because of the way you expressed yourself. i think that drama could surround you, you might have been involved in drama during your childhood, which might have created psychological blockages that affected self expression.
you might have been shunned away for being too kind. i feel like you could have been the kind kid who got bullied a lot for no reason. could have some health issues that you are forced to work through, and you will be very blessed once you do. i feel like you are forced to work under a lot of pressure in your work place and this effort would be greatly appreciated.
if you have this, i feel like you might have abandoment issues because of some past trauma related to relationships. you might have been criticised to how you connect to others and this might have led to an isolation. might have had difficulties in marriages, and the damage caused by them might have also made you isolated.
this is very intense. with this placement, and individual could have gone through a lot of transformative experiences while developing. this might have been very discouraging to them, and any time they tried to rise up they were punished. however, with this aspect, i feel like all these things forced you to reach a higher, purified version of yourself.
SAGGITARIUS/9TH HOUSE
9, 21°
you could be very fascinated with spirituality and be shamed for it. you could say that you are spiritually gifted, but there might have been times where people did not believe you. you might find yourself fearing abandonment from people from different cultural backgrounds. you could be very wise, but maybe nobody took you seriously until you grew up.
CAPRICORN/10TH HOUSE
10, 22°
might have been very affected by male figures, like father, boss, and such. IF you are healed, i feel like you could feel very secure around masculine people and benefit a lot from them and if not, i feel like some insecurities related to abandoment might arise because of their behaviour. if you are a woman, you could have female rage because such presences.
AQUARIUS/11TH HOUSE
11, 23°
might have abandonment issues because of friendships that were gained in an online environment or in large groups. i feel like you might be an idealsitic person, but people never respected your ideas until they actually saw achievements of yours if you had any. might be very quiet in friend groups.
PISCES/12TH HOUSE
12, 24°
with this placement, you might have been prone to delusions during developing. like saggitarius/9h, i feel like you could have be highly intuitive but people could take advantage because of that. you might have been idealising people and things and you might have suffered because of that. i think you are an empathetic individual, but you could have been shamed for it and shunned away.
A/N a more in depth study on this asteroid will be on my patreon SOON.
if these do not resonate, consult the PERSONA CHART of this asteroid. also, if the degree of the placement is low(close to 30°) it may mean that the impact of this asteroid might not be felt as intensely. (29° AND 18° MAY MAKE AN EXCEPTION) of course, the impact of this asteroid also depends on the other planets/points/asteroids surrounding it. - however, in my opinion, the intensity of this asteroid may not be smoothened in the case of the following placements of degrees: saturn/cancer/mars/mercury degrees are bound to saturn/cancer/mars/mercury/pluto.
